摘要

PROBLEM TO BE SOLVED: To provide a composite spray coating film capable of exhibiting multifunctional performance such as corrosion resistance characteristic of metal glass simultaneously with a cermet-specific function primarily such as wear resistance by incorporating a metal glass component while a cermet component is a main component.SOLUTION: A composite spray coating film is formed by spraying simultaneously of first powder (cermet powder) for spray coating made of hard particles made hard with metal and second powder (metal glass powder) for spray coating made of metal glass in amorphous phase. The constitution rate of the first coating component (cermet component) made of the hard particles made hard with the metal to the whole of the first coating component and the second coating component (metal glass component) made of the metal glass in amorphous phase in combination exceeds 40% and is equal to or less than 95%.
