  • Publication number: 20190193195
    Abstract: The present invention is intended is to improve the corrosion resistance of an overlay used in a nuclear power plant, and to reduce dissolution of cobalt from an overlay. The corrosion and wear resistant overlay is formed along a surface of a base by laser lamination modeling, and is configured from a plurality of metal layers of a Co-base alloy. The thickness of carbide eutectics that precipitate in the metal layers is the largest in the metal layer closest to the base, and is gradually smaller in the metal layers farther away from the base. The intensity of the laser beam applied to form layers by laser lamination modeling is adjusted so that the carbide eutectics that precipitate in at least the outermost metal layer have a controlled size of 10 ?m or less.
