Manufacturing method of Ni-Fe-B alloy plating film, Ni-Fe-B alloy plating film and wear resistant member using it

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a Ni—Fe—B alloy plating film capable of forming a Ni—Fe—B alloy plating film having higher hardness on the surface of an object to be plated without heat treatment. SOLUTION: A plating bath including a nickel supply source, an iron supply source and a boron supply source is adjusted, a metal object to be plated is immersed in the plating bath, and 10 A / dm2 or more and 20 A in the plating bath. By performing electroplating with a current density of less than / dm2, a Ni—Fe—B alloy plating film is formed on the surface of the object to be plated. [Selection diagram] Fig. 3
