The present invention provides an alloy member having a metal oxide film that can be formed into a film by a simple method at low cost and that can suppress volatilization of Cr, which causes fuel cell degradation, more than conventional high-cost materials. A method for producing an alloy part, comprising the following steps: a coating treatment step of coating a Fe-Cr-based alloy substrate with Co; an oxidation treatment step of performing a base coating in a moisture-containing atmosphere after the coating treatment step Oxidation of the material. |
