Abstract

PURPOSE:To improve the adhesion of a diamond film to a substrate by coating the substrate with a hard carbon film by a vapor phase synthesis method and then coating the substrate with the diamond film by CVD or PVD. CONSTITUTION:A silicon layer is formed on a substrate by pretreatment and the substrate is coated with a hard carbon film 2 having a carbon-based amorphous structure by a vapor phase synthesis method in a flow of a hydrocarbon- based gas. The substrate is then coated with a diamond film 3 having the same crystal structure and compsn. as natural diamond by CVD from a carbon-contg. gaseous compd. with a hot filament or microwave plasma or by PVD with charged carbon particles. Thus, the diamond film 3 can be formed on the substrate of various metals, glass, ceramics, etc.
