  • Mechanisms for Grip-and-Release Process of Adhesion Contact Using Material with Variable Elastic Modulus

    Y. Sekiguchi, L. Lei, P. Hemthavy, K. Takahashi

    Adhesion mechanisms with and without a defect for gripping and releasing objects are proposed, considering the adhesion between a semi-infinite elastic body and a rigid object with a sinusoidal surface roughness. These mechanisms are investigated theoretically. The total energy consists of the elastic term, the interfacial adhesion term, and the mechanical potential energy term due to the external pressure. The grip-and-release process is discussed in terms of the changes in the total energy and the contact width. The gripping stress can be expressed as a function of the elastic modulus. Using polymers with variable elasticity, the grip-and-release process is demonstrated experimentally and discussed in terms of the theory. (C) Koninklijke Brill NV, Leiden, 2010

    Adhesion between a flat silicon rubber and an aluminum body with sinusoidal surface roughness is investigated. Hysteresis loops are observed in the relation between the external pressure and the contact width. The hysteresis is considered as the effect of the surface subroughness, and is successfully interpreted by a theory of the elastic contact between an infinite elastic body and a rigid body with single sinusoidal surface roughness. The effect of the sub-roughness is approximately expressed using a treatment of the energy dissipation. The work of adhesion and the parameter corresponding to the energy dissipation ratio are obtained from the measurements. The pressure required to snap to perfect contact and to separate the contact can be well predicted using the work of adhesion and these parameters.

  • Expansion of the applicability of the modified embedded atom method to non-bulk systems

    In order to expand the applicability of modified embedded atom methods (MEAMs) from bulk to non-bulk systems, a dimer reference MEAM (DR-MEAM) is proposed. In this method, a diatomic structure is selected as the reference structure and the parameters for Cu are determined from the properties of the equilibrium bulk structure and some clusters, in order to obtain a wide range applicability from the bulk to the non-bulk systems. In the determination of the parameters, the lattice constant, the binding energy, and the bulk modulus are used as the bulk properties and the binding energy, the bond length, and the bond angle of Cu, (n 2, 3, 4) are used as the clusters properties. Several other properties of Cu are calculated by the DR-MEAM and the parameters, and they are compared with experimental results and DFT results to examine the present method and parameters. It is found that they exhibit good agreements for many properties such as the lattice stability, the shear elastic constants, the vacancy formation energy, the surface energy of low index crystal surfaces, the binding energy of the Cu clusters (n >= 5), etc. It is suggested that the present method and parameters have a wider range of applicability than the conventional MEAMs. The DR-MEAM does not exhibit good agreement only for the bond angle of Cu(3) and Cu(4) This disagreement seems to suggest a theoretical limitation of the embedded atom method approximation.

  • An analytical approach for the adhesion of a semi-infinite elastic body in contact with a sinusoidal rigid surface under zero external pressure

    An analytical approach for the adhesion of a semi-infinite elastic body in contact with a sinusoidal rigid surface under zero external pressure is presented. Although Johnson (Int. J. Solids Struct. 32, 423 (1995)) has proposed an analytical solution for a slightly wavy surface, while Zilberman and Persson (Solid State Commun. 123, 173 (2002); J. Chem. Phys. 118, 6473 (2003)) have given a numerical solution for a highly wavy surface by considering the curvature of the contact area in the calculation of the interfacial term of the total energy, our solution is not only for small amplitude of roughness (i.e., the slightly wavy surface as Johnson's) but also for large amplitude of roughness (i.e., the highly wavy surface as of Zilberman and Persson). Our solution considers the curvature of the contact area as do Zilberman and Persson. Our results which are obtained for the total energy and equilibrium condition of the system agree with both Johnson's and Zilberman and Persson's results. The effects of the material constants and the surface roughness on the adhesion are clearly expressed and discussed.

  • Geckos' foot hair structure and their ability to hang from rough surfaces and move quickly

    Geckos generate the necessary adhesion force through their foot hair. The direction of the gecko's foot hair is not perpendicular to its finger surface, giving compliance to the hair. The effect of this compliance on the adhesion force is analysed and expressed theoretically in terms of contact mechanics. We conclude that the compliance of the foot hair is sufficient to generate the large adhesion force necessary for adhesion to rough surfaces, and that the structure of the seta with the spatulae allow the normal adhesion force to be controlled, allowing the gecko to make quick steps.

    Agreeing on a method to identify interfaces is a desirable step in order to build a database of interfacial energy. So far, the expression Sigma X Interface has been used to identify interfaces. Unfortunately, this conventional method cannot express arbitrary interface geometries. In the present work, we review interface geometries and propose a systematic Orientation Method based purely on geometrical considerations that can express arbitrary twists and slipping of interfaces.

  • Capillary force with a concave probe-tip for micromanipulation

    This letter describes the measurement of capillary force with a concave probe-tip for micromanipulation. Using an electric balance, we measure the capillary force for a given gap distance between a spherical object and a concave surface coaxially fabricated on a cylinder. We used three different materials (glass, stainless steel, and polytetrafluoroethylene) to check the influence of contact angles. The results are in good agreement with the theoretical prediction expressed in the normalized form; these indicate that a concave tip can generate a much larger capillary force than a flat one, provided the tip is designed to fit the convex surface of the object; moreover the results clarify that the more wettable a material is, the greater capillary force it can generate. This suggests micromanipulation by capillary force should be more practical by using probes with concave tips specifically designed for the object. (c) 2005 Americian Institute of Physics.

  • Dimer reference embedded atom method (DR-EAM) and its application to vacancy formation energy of FCC metals

    Embedded atom method (EAM) has been successfully applied to investigate surface properties and simulate diffusion phenomena, which do a great help to study micro-joining process. However, because its theory and parameterization are based on bulk system it fails in solving some problems of non-bulk system. In order to increase the applicability of EAM to non-bulk system, a new scheme of EAM, DR-EAM is proposed. In this scheme, the dimer structure is selected as a common reference structure and the parameters are derived from dimer and some bulk properties. In this work, the DR-EAM parameters of 7 kinds of FCC metals are renewed by revising the modeling system and including some experimental data of dimer. The features of their energy-distance curves are discussed and it shows the need of including angular dependency of electronic density. The vacancy formation energies, which play an important role in the diffusion process, are calculated and compared with experimental data.

    A comparative study has been performed for silicon microclusters, Si-3 and Si-4, considering fifteen different empirical potential energy functions. It has been found that only two of the empirical potential energy functions give linear structure more stable for Si-3, the remaining potential functions give triangular structure as more stable. In the case of Si-4 microclusters eight potential functions give open tetrahedral structure as more stable, two functions give perfect tetrahedral as more stable, three functions give square structure as more stable, and two functions give linear structure as more stable.

    As the size of object diminishes, the effect of adhesional forces grows stronger for micro-manipulation and so. The capillary force generated by a liquid bridge can be greater than both the capillary force generated by another bridge and the adhesional force because the capillary force can be controlled by regulation of the liquid volume. We propose a micro-manipulation method based on the regulation of liquid bridge volume. A numerical investigation to estimate the capillary force from a given liquid volume is also presented, and four phases of capillary force curves are obtained from it. If an object is supported by two liquid bridges, we can predict which bridge collapse by a stability analysis for the wide range of liquid volume using the force curve.

    A new scheme of the modified embedded atom method (MEAM) is developed by modifying the analytic form of the embedding function. The new MEAM parameters for Mo, W, V, Nb, Ta and Fe have been determined by relating them to not only bulk properties but also some non-bulk properties. The new scheme was applied to calculate the elastic stiffness of the crystal, the vacancy formation energy, the lattice stability, the surface energies for low-index crystal faces and the bond length and the binding energy for the dimer. The results give a fairly good agreement with the experimental data.

    Using a simple discharge circuit, we have investigated effects of the circuit parameters on glow-to-arc transition behaviour. A direct current power source is used with a capacitor and resistors. Plasma is generated between thoriated tungsten electrodes at atmospheric pressure in argon. Current and voltage are recorded while capturing plasma images. A variation of the charge on the capacitor causes a fluctuation in discharge current. Due to the current fluctuation, the electric power dissipated between the electrodes increases during a temporary glow phase and decreases during a temporary arc phase. The cathode tip has been heated in the glow mode and a glow-to-arc transition occurs finally. The current fluctuation can be reduced by increasing the resistance. The temporary arc and glow durations are affected by the time constant of the circuit.

    Boundary element method is one of the most powerful tools to solve partial differential equations. However, it takes a lot of computational time when applied to an actual problem with a large number of unknowns,
    In this research, the binary tree structure with tight bounds and the downward pass for this structure are adopted for the fast multipole method to reduce the number of M2L translations, thereby further reducing the computational time. Furthermore, the recurrence formulae to calculate the multipole moments of a triangular element are derived.
    The fast multipole boundary element method using the binary tree structure with tight bounds is developed and the analyses of an electrostatic force acting on a metal micro particle above a complex structure are performed to confirm the effectiveness of this method.

    This letter describes a calculation of a voltage sequence to obtain kinetic control of a particle for nonimpact electrostatic micromanipulation. The system consists of conductive objects: A manipulation probe, a spherical particle, and a substrate plate. The particle, initially adhering to the probe tip, is detached by an applied voltage. The electrostatic force acting on the particle during its movement to the substrate is calculated by a numerical boundary element method. We determine the voltage and time sequence for nonimpact deposition of the particle onto the substrate by considering the total work to the particle. The calculation provides the power source requirements for nonimpact particle deposition. (C) 2003 American Institute of Physics.

    A new scheme of modified embedded atom method (MEAM) is proposed in this paper. The analytic form of the embedding function is modified. All the parameters of MEAM have been reset by relating them with bulk properties and some non-bulk properties, for example, the bond length of a dimer and the change of surface interlayer distance. The new scheme has been applied to calculate the elastic stiffness of crystal, the vacancy formation energy and some properties of non-bulk systems such as the surface energies for low index crystal faces, the bond length and the binding energy for a dimer. The results are compared with the experimental data and get a fairly good agreement.

    During micromanipulation, the influence of gravitational force becomes extremely small. The adhesional force is more significant for smaller objects. An adhered object can be detached by electrostatic interaction. In our earlier study, the electrostatic force generated by an applied voltage and the voltage required for detachment have been theoretically analyzed using the boundary element method (BEM). The system consists of a manipulation probe, a spherical microparticle, and a substrate plate. These objects are all conductive. In this study, the voltage for detachment of a microparticle with a 30-mum diameter is experimentally clarified, and is revealed to be in good agreement with the voltage predicted by BEM analysis. In addition, phenomena other than detachment are discussed based on observations through an optical video microscope. These results provide us with knowledge about the strategy for reliable electrostatic micromanipulation. (C) 2003 American Institute of Physics.

    In this paper, the kinematics of mechanical and adhesional micromanipulation using a needle-shaped tool under a scanning electron microscope is analyzed. A mode diagram is derived to indicate the possible micro-object behavior for the specified operational conditions. Based on the diagram, a reasonable method for pick and place operation is proposed. The keys to successful analysis are to introduce adhesional and rolling-resistance factors into the kinematic system consisting of a sphere, a needle-shaped tool, and a substrate, and to consider the time dependence of these factors due to the electron-beam (EB) irradiation. Adhesional force and the lower limit of maximum rolling resistance are evaluated quantitatively in theoretical and experimental ways. This analysis shows that it is possible to control the fracture of either the tool-sphere or substrate-sphere interface of the system selectively by the tool-loading angle and that such a selective fracture of the interfaces enables reliable pick or place operation even under EB irradiation. Although the conventional micromanipulation was not repeatable because the technique was based on an empirically effective method, this analysis should provide us with a guideline to reliable micromanipulation.

    The Modified Embedded Atom Method (MEAM) is applied to dimers of several materials whose parameters are published by Baskes. For some materials, the MEAM is found to return fatal errors which never arises in bulk systems. The problem of the fatal error is found to be because of a formalism which calculates the background electron density, and the usage of an original formalism is found to prevent the problem. Since the dimer is the most non-bulk system, this problem has to be considered in the application of MEAM to non-bulk systems. The MEAM calculation has been retried for all of the dimers by using the original formalism. The results by the MEAM are compared with density functional theory (DFT) calculations. The usage of the original formalism returns the consistent results for most of the dimers. This suggests that the original formalism has to be used for the background electron density calculation, if the MEAM would be applied to non-bulk systems. It would also suggest that the MEAM parameters should be modified for some materials (Mo, Cr, C).

The manipulator and the substrate are cylindrical, and axial symmetry is assumed. Although a numerical method is used to solve the equations, all parameters are normalized. The effect of the shape parameters on the Coulomb force is systematically calculated. The force is independent of system size and depends on the relative shape of the system. The force is proportional to the applied voltage raised to the second power. The force generated by the Coulomb interaction is compared with the adhesion force deduced from the Johnson-Kendall-Roberts theory, and the voltage required for detachment is clearly expressed. The possibilities and limitations of micromanipulation using both the adhesion phenomenon and Coulomb interaction are theoretically discussed. (C) 2001 American Institute of Physics.

    Recently, techniques of arranging micrometer-sized objects with high repeatability under a scanning electron microscope (SEM) are required to construct highly functional micro-devices. Since micro-objects tend to adhere to other objects mainly by electrostatic force, manipulation techniques by adhesive force are often taken in basic researches where micro-objects are studied. These techniques, however, still do not achieve the desired repeatability, since many of these are used just for the empirical effectiveness. Some even include the process of trial-and-error. Thus, for this paper, we analyze micro-object operation theoretically by considering adhesion and rolling-resistance factors in the dynamic system consisting of a sphere, a needle-shaped tool, and a substrate. Through this analysis, we show that it is possible to control the fracture of the contact interfaces of the system selectively by determining the tool-loading angle reasonably. Based on the analysis, we also proposed the practical method of the pick and place operation of a micro-sphere under an SEM.

    A modified embedded atom method (MEAM) potential is applied (110) surfaces of several face-centered cubic metals. Surface energies of Au, Pt, and Pb an calculated for the ideal (110) structure, the missing row structure, and the missing column structure, where the last structure is defined in the present paper. The energies calculated for the three structures are discussed with the experimental results obtained from low energy electron diffraction. The MEAM calculations suggest that the missing row structure is most stable for Au and Pt, the ideal structure is most stable for Pb, and the missing column structure is unstable for all cases. These trends show a good agreement with the experimental facts. The position of surface atoms is compared with experimental results. They are in fairly good agreement with each other.

    The Modified Embedded Atom Method (MEAM) is applied to Si(lll) surfaces. The surface reconstruction is simulated for N X N DAS structures and surface energies are calculated to be 1571, 1530, 1524, and 1549 mJ/m(2) for N = 3, 5, 7, and 9, respectively. It is clearly shown that the 7 X 7 DAS structure is most stable in these NXN DAS structures, and 5 X 5 is more stable than 9 X 9. These results correspond to our experimental knowledge. Ln principle, (M)EAM is a good method to calculate bulk properties. This report suggests that the MEAM is a useful tool also for surface problems. (C) 1999 Elsevier Science B.V. All rights reserved.

    To understand adhesional phenomena, it is significant to obtain force curves between surfaces, because the relationship between the force and the tip-sample distance contains the infomation on surfaces. Usually the stiffness of force measurement system of AFM (Atomic Force Microscopy) is under the order of 10 N/m. The stiffer force measurement system, however, results in more information on surfaces, because higher stiffness lead to the wider range of force curves, secondly because the force curve obtained through the stiffer one describes more precise relationship between relative tip-sample separation and interaction force. On the other hand higher stiffness degrades the force resolution. In this paper three mechanisms are compared i.e., Optical lever system, Double cross cantilever system, and Semiconductor transducer system. With the stiffness under 2000 N/m, Double cross cantilever system shows the highest force resolution. It is suggest that also the Semiconductor transducer system could show the highest force resolution, if the stiffness was larger than 15000 N/m. In ultra high vacuum AES (Auger Electron Spectroscopy), Semiconductor transducer system would be most convenient to manipulate.

    Force curves obtained from an elastic contact theory are shown and compared with experimental results. In the elastic contact theory, a pin-on-disk contact is assumed and the following interaction are taken into consideration: (i) elastic deformation, (ii) the specific energy of adhesion in the area of the contact, which is expressed as the difference between the surface energies and the interface energy, (iii) the long-range interaction outside the area of contact, assuming the additivity of the Lennard-Jones type potential, and (iv) another elastic term for the measurement system such as the cantilever stiffness of an atomic force microscope (AFM). In the limit when the stiffness is infinite, the theory conforms to Muller-Yushchenko-Derjaguin (MYD) theory. In the limit when the surface-surface interaction is negligible, the theory conforms to the analytical theory by Takahashi-Mizuno-Onzawa. In the limit when the stiffness is infinite and the long-range interaction outside the area of contact is negligible, the theory conforms to Johnson-Kendall-Roberts (JKR) theory. All parameters and all equations are normalized and the normalized force curve is obtained as the functional of only two parameters: (1) the normalized stiffness of the measurement system, and (2) the normalized distance which is used in the expression of the Lennard-Jones potential. The force-displacement plots are converted into force-penetration plots. When the long-range interaction is negligible, the normalized force-penetration (F-P) plots superimpose each other. When the long-range interaction is NOT negligible, and before contact (or after separation), the F-P plots also superimpose. When the long-range interaction is NOT negligible, and during the contact, they do not superimpose, although during the first stage of contact the F-P plots are very similar, forming a narrow band. Stiffness of measurement system such as cantilever of AFM and significant figures of measured displacement are important to interpret adhesional force curves. The stiffness and the significant figures of displacement which are required to interpret force curves are deduced and the relation between them are discussed. A stiffer cantilever is more suitable for the interpretation of surface forces. The experimental force-displacement plot obtained from AFM with an Au-coated tip and a Si (100) wafer, is converted into a force-penetration plot. The influence of the nano-scopic shape of the tip or the sample on the force curve could be shown using both the force-penetration plot and the contact theory.

    The force curves were measured in the ultra high vacuum (UHV) chamber of an Auger electron spectroscopy (AES) which is generally used for surface analysis. Contacts were made between a gold sphere of about 200 μm radius and a silicon wafer. The specimens were sputtered by argon ion to clean their surfaces before the contact. No adsobates were observed in Auger spectra obtained from the sputtered surfaces. Contact theory for adhesion between an elastic sphere and a rigid plane is described. This theory is based on Johnson, Kendall and Roberts (JKR) theory and Takahashi theory. The total energy in this system is a sum of the elastic energies in the sphere and the stiffness for the measurement system, the change of the surface energy within the contact region and surface-surface interaction outside of the contact region. The force curves are determined by the stiffness and the characteristic distance parameter of Lennard-Jones potential. Experimental force curves were compared with the theoretical curves. Experimental force curves were influenced by vibration of experimental apparatus. It was suggested that surface-surface interaction was negligible under the order of radius of a gold sphere used to measure. Surface-surface interaction does not become negligible as radius of sphere becomes small. The developed measurement system reveabled informations of interatomic interaction and surface roughness.

    In the brazed joint of natural diamond to Fe-42 Ni alloy made with Ag-Cu eutectic filler including 4.5 wt% Ti, the behavior of titanium segregation changes according to the brazing thermal cycles, which causes the change in joint strength and the fracture mode. The chemical reaction products of diamond and the filler were identified by ESCA and EDS analyses on the fractured surfaces at the brazed interface, where the analyzed surfaces were made using a developed tensile shear test method, in order to propose the model of formation mechanism of the joint structure. The analytical results revealed that such a structure as consists of TiC nucleation surrounded by Ag and/or Cu is preferred as the joint structure. It was also indicated that the segregation of Ti at the joint interface reduces the bonding strength, where the fracture is liable to occur at the interfaces of diamond-Ti and/or TiC-Ti. The relation between the joint structure and the strength was also discussed using the disregistry values calculated in the previous report. The structure formation models of the interface between diamond and brazing filler metals were proposed to explain the change in the structure and strength of the joint made by different cooling rates. © 1995, JAPAN WELDING SOCIETY.

  • INFLUENCE OF THE STIFFNESS OF THE MEASUREMENT SYSTEM ON THE ELASTIC ADHESIONAL CONTACT

    An elastic contact theory is described to reveal the effects of the stiffness of the measurement system on the adhesion behavior. The point contact is treated in an elastic continuum limit, taking into account the energy change from the surface to the interface within the contact region. The contact area is determined under Hertz's assumptions. The stiffness of the measurement system is taken into account and the total energy is defined as E(total) = E(elastic) + E(interface) + E(stiffness). The contact radius, the displacement, the force, and the total energy are normalized and their relationships are discussed. In the limit when the stiffness is infinite, our approach conforms to the Johnson-Kendall-Roberts (JKR) theory. The force at the initial contact is discussed as well as the force required to separate samples. The ratio of these forces can be written as a function of only one parameter (kappa), which is concerned with the stiffness. A simple asymptotic relation is derived between the force ratio and the parameter kappa. It is suggested that the radius of the contact tip can be estimated from Young's modulus, the Poisson ratio, the stiffness, the separation force, and the force ratio. The force curves and their hysteresis loops are deduced and discussed.

    Natural diamond has been brazed to Fe-42Ni alloy sheet using Ag-Cu eutectic filler including active metal of 4.5 wt% Ti, in order to investigate on the relation between the segregation behavior of the active metal to the brazed interface and the joint strength. The examination of the effects of brazing thermal cycles on the reaction products and titanium segregation behavior at the diamond-filler interface showed that the microstructures at the interface were dendrite and cell structure in case of cooling rate of 12 K/sec and 1.5 K/sec respectively, and that the active metal (Ti) was not detected by EDS in the both structures. This suggests that titanium segregation at the joint interface and the grain boundaries occurs as a result of exclusion of titanium out of Ag-Cu eutectic crystals accompanied by the crystal growth. The joints were fractured at the interface between diamond and brazing filler using a developed tensile shear test method to get the joint strength and the fractured surfaces at the interface. The strength of the joint made by the cooling rate of 1.5 K/sec was higher than that made by the rate of 15 K/sec. The disregistry values were also calculated from the mismatch of surface orientations and lattice constants at the bonded interface. The results showed that the disregistry of diamond and TiC to Ti were remarkably larger than those to Cu and Ag, which corresponded to the joint strengths and the fracture paths. © 1994, JAPAN WELDING SOCIETY.

    When hot pressing is used to fabricate the fiber reinforced materials (FRM), hot pressing process parameters should be selected so as to satisfy the following two necessary conditions, i.e., (1) the deformation and the adhesion of the matrix foil must be completed, (2) the thickness of the reaction layer at the matrix/fiber interface must be smaller than the critical value which is derived from the Griffith's theory. In order to predict the deformation of matrix foils, a model was proposed, where plastic and creep deformation were taken into account. The thickness of the reaction layer was predicted on the basis of the diffusion controlled mechanism. These calculations provide a consistent and unified interpretation of experimental data for Ti-matrix FRM. An algorithm of the determination of hot pressing process parameters was proposed. According to the algorithm, Ti3Al matrix FRM was formed to demonstrate the applicability of the algorithm. The tensile strength of the FRM was found to be about 1200 MPa at the temperature range from 300 K to 1000 K. © 1994, JAPAN WELDING SOCIETY. All rights reserved.

    The jelliumlike free-electron model is used, and the effective one-electron potential v(eff) is approximated to be the step-function which is shifted to satisfy the neutrality of the charge. The eigenfunctions can be obtained in analytic form. Although not self-consistent, the calculated distribution of the electron density is very similar to the self-consistent field (SCF) jellium results by Lang and Kohn. A simple formula for the surface energy is obtained. The surface energy is given as a function of the Fermi energy and the work function. The formula suggests that the surface energy is sensitive to the Fermi energy and is not sensitive to the work function, i.e., the surface energy is approximately in proportion to the fourth power of the Fermi energy. The calculated surface energy approaches the SCF jellium results by Lang et al. and the structureless pseudopotential results by Perdew for small electron density.

    A titanium film was deposited on a sapphire substrate by electron beam deposition and a valence Auger analysis was performed on this after annealing. We mainly analysed the annealed interface between titanium and sapphire. The effect of argon ion beam and electron beam bombardment on sapphire is examined. Several characteristics of spectral shapes concerning Ti-O and Al-O bonds were obtained from the surface-oxidized titanium film and Al2O3 bulk respectively. Although the Ti-sapphire interface was affected by argon ion and electron beam bombardment, the interfacial spectra have characteristics of Ti-O and Al-O bonds. However, it was difficult to find any evidence for the existence of Ti-Al bonds from the characteristics of the spectral features only.

    The shrinkage behaviour of voids arrayed on a bond-interface (grain boundary) is analyzed by computer simulations. It is assumed that surface and interface self-diffusion operate in series. The junction between the void-surface and bond-interface is treated as a tip with a dihedral angle theta. Two numerical models are proposed to discuss the effect of interface and surface tensions on the void shrinkage. One of them always restricts theta to the value of the equilibrium balance (model 1). In the other (model 2), the equilibrium balance is ignored, i.e. the change in theta (free dihedral angle) is considered during the void shrinkage. For discussing the rate controlling step, model 2 is essentially the same as model 1. But, when the void shrinkage is controlled by the interface diffusion, they give void shapes quite different from each other, i.e. when the diffusivity ratio f >> 1 (f = 2-delta-sD(s)/delta-bD(b), where delta-sD(s) and delta-bD(b) are produced by the thickness of the diffusion layer and the self-diffusion coefficient for the surface and interface, respectively), model 1 gives the equilibrium void shape but model 2 only exhibits the stationary void shape. The void morphology is not only influenced by the prescription of the equilibrium balance but also by the diffusivity ratio f. The stress and temperature dependence of the void shrinkage can roughly be expressed by 2-delta-sD(s)delta-bD(b)/[(2-delta-sD(s) + delta-bD(b))P(n)], where P is the bonding pressure and n the stress exponent. If theta is prescribed by the equilibrium balance, n increases from -1 to -0.3 with decreasing P. But, if theta changes, n is about -1. It is verified by experiments that the dihedral angle is not always constant and changes as increasing net stress is applied to the bond-interface. It is suggested that model 2 more exactly predicts the void-shrinkage process than model 1 as the pressure is increased.

    The valence Auger spectra have been studied in order to understand interatomic chemical bonding across the interface between metals and ceramics. SiO2 was adopted as the ceramic and Ti was used as the metal. Ti/Si interface was also analized to comprehend the characteristic features of Si-O, Ti-O and Ti-Si bond in spectra. Ti was deposited on SiO2 and Si substrates under high vacuum environment about 5 × 10-4 Pa. Ti/SiO2 was annealed at 473K for 1800s. Ti/Si was annealed at 823K for 3600 s. Some of the spectral feature observed on the Ti/Si interface were applicable to understand the chemical bonding at the Ti/SiO2 interface. The Ti-0 bond was detectable at the interface by the intensity ratio of Ti-LM23M45/Ti-LM23M23. The Si-0 bond was also detectable from the energy of Si -LVV peaks. It was found to be difficult to comfirm the existence of Ti-Si bonds at the Ti/SiO2 interface. A damage induced by Ar- and electron-bombardment was observed. It didn't disturb the detection of Ti-O and Si-O bonds. © 1991, JAPAN WELDING SOCIETY. All rights reserved.

    The valence electronic structure of the Ti/SiO2 interface was discussed by analyzing their Auger spectra. The change in the intensity ratio of SiO2-L23V1D+Si-L3M23M23/SiO2-L23V1V1 with Ti contents were helpfull to confirm the interfacial Ti-Si bonds under the condition that the electronic dose were kept constant at each analyze-point through the interface. This concept was also applied to annealed interface of Cr/SiO2 and Cu/SiO2. M-O or Si-O bonds were detected at the interface. The possibility of the existence of M-Si bonds were suggested from the Auger intensity ratio. The transition elements which exhibit small number of 3d electron, such as III a-VI a metals, tend to lose the metallic property in electronic structure. © 1991, JAPAN WELDING SOCIETY.

    記述言語：英語  

    The process of solid state diffusion bonding is analized, noting the transient behaviour of interface-. diffusion, which is an atom-flow along a bonded interface-boundary. A non-linear partial differential equation for the interface-diffusion is led by proposing a two-dimensional bonding model. Numerical calculations are performed with Euler method. It is indicated that an enhancement of the bonding process is caused by the transient behaviour when the bonding pressure is frequently removed, although it is negligible in a conventional diffusion bonding. So, “pulse-pressure bonding”, in which the pressure is repeatedly applied at intervals of τoff(pressure-off interval), is proposed according to the calculated results. Influence of τoffon the enhancement-effect is numerically and experimentally examined. It is shown that τoff is a very important factor as a period of “relaxation” in order to attain an effect of the transient behaviour. And also, it is suggested that the enhancement-effect becomes striking with reducing the pressure-on interval τon, when τoff is suitablely determined. It is stated in conclusion that the bending process enhanced by the transient behaviour is successful even if τoffis less than zon, that is, the pulse-pressure method can be useful to enhance the bonding process under a high vacuum condition. © 1986, JAPAN WELDING SOCIETY.
