Title: Yasuo Fukui: Innovator in Diamond Coating Technology
Introduction
Yasuo Fukui is a notable inventor based in Toyokawa, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced coatings for tools. With a total of two patents to his name, Fukui's work focuses on enhancing the durability and performance of cutting tools through innovative diamond coating technologies.
Latest Patents
Fukui's latest patents include a tool having a boron-doped diamond coating. This invention aims to provide a tool that ensures improved durability even when a diamond coating containing boron is formed. The diamond coating consists of a first layer that is formed on the surface layer side and is regarded as containing no boron. The second layer, positioned on the side of the base material, contains at least 1000 ppm or more of boron. By forming a first layer with larger compressive stress on the surface layer, the invention reduces the likelihood of crack generation during the process, thereby improving the tool's durability.
Another significant patent is for a hard multilayer coating, which is designed to be disposed on a body. This coating includes a first layer in contact with the body, consisting of TiAlCrXN, where 'X' represents carbon or oxygen. The second layer is a mixture layer of TiAlCrXN and TiAl(SiC)XN, or a multilayer with alternating sublayers. The third coating layer, constituting the outermost layer, consists of TiAl(SiC)XN. This innovative multilayer coating enhances the performance and longevity of tools.
