发明名称 METHOD OF MANUFACTURING CORROSION RESISTANT METALLIC MEMBER AND CORROSION RESISTANT METALLIC MEMBER
摘要 PROBLEM TO BE SOLVED: To provide a method of manufacturing a corrosion resistant metallic member which has a high degree of a corrosion resistance and is particularly useful as a separator for fuel cells and to provide a corrosion resistant metallic member. SOLUTION: When thin noble metal layers 21b and 31b are formed on both surfaces of a metallic base material and are molded to peak and valley shapes by compression working, pinholes generated in forming the thin-film layers remain as 42a, 45a, 51a, 54a, etc., and the metallic base material is exposed in these segments. These exposed sections are treated by a liquid phase system containing a peroxide or ozone in order to prevent the corrosion thereof. Oxides 61, 62, 71 and 72 are formed by this treatment, by which the thin-film layers are restored.
