Abstract: Resistance of iron, iron-chromium and iron-chromium-nickel alloys to corrosive attack by sulfur compounds at temperatures above 500.degree. F. is improved by pretreating the metal under controlled conditions to form an extremely thin submicroscopic oxide film which serves as a corrosion resistant barrier.

Abstract: Provided is an alloy material including a metal oxide thin layer that can be formed using a simple method at low cost and can further suppress volatilization of Cr, which causes deterioration of a fuel cell, compared with a case where conventional expensive materials are used. Disclosed is a manufacturing method for an alloy material including a coating treatment step for coating a substrate made of a Fe—Cr based alloy with Co, and an oxidation treatment step for performing oxidation treatment on the substrate in a moisture-containing atmosphere after the coating treatment step.
