Method of surface-treating metal component

摘要

Provided is a method for surface-treating a metal component, whereby a pseudo-plated layer can be formed on a surface of a metal component, and quality equivalent to plating or other coating process can be obtained. The method includes a chemical polishing step scraping a surface of a base plate formed into a given shape through chemical polishing by 0.5 micrometer or more, and a heat treat pseudo-plating step forming a pseudo-plated layer on the surface through a heat treatment conducted by heating the base plate at a solution treatment temperature or above, for example, 850 degrees C. or above, preferably approximate 1040 degrees C., in a reducing atmosphere after the polishing step.

1. A method of surface-treating a Fe—Cr—Ni stainless steel component, comprising:
a polishing step polishing a surface of the Fe—Cr—Ni stainless steel component formed into a given shape by chemical polishing; and a heat treat pseudo-plating step forming a pseudo-plated layer on the surface through a heat treatment conducted by heating the Fe—Cr—Ni stainless steel component having the surface being in a chemically-polished state at a solution treatment temperature or above in a reducing atmosphere after the polishing step.
