Abstract
PURPOSE:To form a layer contg. Al, Cr, which is excellent in corrosion resistance and oxidation resistance, on the surface of an iron group matal, by heating the iron group metal embedded in a mixture comprising Al powder and Cr powder as main agents and fluoroborate as a promotor. CONSTITUTION:Fe base metal, Ni base metal, or Co base metal is embedded in a mixture comprising Al powder and Cr powder as main agents, and fluoroborate as promotor, then it is heated pref. at a temp. 600-1,000 deg.C to form an Al.Cr layer on the surface. It is possible to conduct this method in the air. This method is applied to manufacture of parts of jet engine, or a rocket engine, which requires corrosion resistance and oxidation resistance.
