<p>A mechanical part brought into contact with a member selected from the group consisting of paper, rubber, plastics, resin, ceramics, and metal, comprises a substrate of an iron series metal and a surface layer formed on a surface of the substrate and containing chromium oxide (Cr2O3) as a major constituent. The chromium oxide (Cr2O3) is a material converted by heating a chromium compound, and an intermediate layer containing a reaction product between the substrate and chromium oxide in the surface layer is formed at an interface between the surface layer and the substrate.</p> |
