ABSTRACT:
Machine parts to be brought into contact with an elongated fibrous member each consists of a substrate of an iron series metal and a surface layer which has high wear-resistance and a good sliding property, and which contains chromium oxide as a major constituent. The chromium oxide is converted from a chromium compound upon heating. An intermediate layer containing a reaction product between the chromium oxide in the surface layer and the substrate is formed at an interface between the surface layer and the substrate.
