Abstract
A method of forming a sufficiently thin, highly amorphous and homogeneous glass-like carbon film on the surface of a titanium metal with high efficiency. In this method, the surface of a titanium metal is polished by e.g. buffing with emery paper and alumina or chromium suspension as polishing agents to form a mirror surface. A dense and rigid titanium oxide film layer is formed on the mirror surface. The surface of the titanium oxide film is then subjected to plasma heating in an atmosphere containing a hydrocarbon gas under a gas pressure of 0.1-30 Torr at 400-1100.degree. C. to form a glass-like carbon film thereon.
