发明名称 Hard carbon coating-clad base material
摘要 The hard carbon coating-clad base material of the present invention comprises a base material, a substratal metal coating formed on the base material by a wet plating process, an intermediate metal coating comprising a titanium or chromium coating formed on the substratal metal coating by a dry plating process and a silicon coating formed on the titanium or chromium coating by a dry plating process, and a hard carbon coating formed on the silicon coating by a dry plating process. According to the present invention, a highly reliable hard carbon coating which is excellent in corrosion resistance, adhesion and abrasion resistance can be formed even on brass or an iron base material having poor corrosion resistance, such as SK steel and martensitic and ferritic stainless steels.
