    By the "dynamic annealing process", which superimposes the sputtering process and the vacuum annealing process, we succeeded in pioneering the large-area synthesis of hBN nanosheets and graphene. It can be said that the realization of the synthesis of 2D nanomaterials by the physical vapor phase growth method has created a technological breakthrough of "safe, simple, and large-area, high-quality synthesis of BCN-based nanomaterials." Furthermore, it was clarified that by mixing hBN nanosheets into an amorphous carbon film, heat resistance is greatly improved, and it is possible to produce a film that can withstand heating above 600 °C in an atmospheric atmosphere.

    This research aims to develop novel mechanical coating materials consisting of carbon, boron and nitrogen, which is named “adamant” thin film coatings. Ternary diagram was described using measured data set of mechanical properties of various adamant films, and systematization of adamant films is performed on the diagram.
    Carbon contents has significant influence for the mechanical properties of adamant films. Nanoindentation hardness of the film sharply decreased when the carbon content exceeds 50at.%. In contrast, the thermal resistivity of the film was improved by decreasing the carbon content. It is interesting result that the wear resistance improves when small amount of B was added in DLC film. Moreover, adhesion of platelet was suppressed on the B containing amorphous carbon films. These results lead us to open novel mechanical coatings using adamant materials.
