CORROSION AND WEAR RESISTANT OVERLAY, METHOD FOR FORMING CORROSION AND WEAR RESISTANT OVERLAY, AND CORROSION AND WEAR RESISTANT VALVE

The invention is intended to improve the corrosion resistance of an overlay used in a severe environment such as a nuclear power plant, and to reduce dissolution of cobalt from an overlay. The corrosion and wear resistant overlay 7 is formed along a surface of a base 2 by using laser lamination mode...
