摘要： PROBLEM TO BE SOLVED: To reduce corrosion of a metallic material, such as intergranular stress corrosion, without using other equipment for hydrogen injection and the like. SOLUTION: TiO 2 in a photocatalytic n-type semiconductor is deposited on or applied to a surface of a metallic material. Exposure to high temperature water generates a thermally excited current to cause a potential drop. An increase in water temperature lowers corrosion potential. A temperature of 280°C can establish a corrosion potential causing no stress corrosion cracking to reduce corrosion of the metallic material. COPYRIGHT: (C)2003,JPO
