POWDER FOR FORMING THERMAL SPRAY LAYER, CERMET THERMAL SPRAY LAYER, CERMET-COATED MATERIAL, AND MANUFACTURING METHOD OF CERMET-COATED MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a powder for forming thermal spray layer, used for forming a cermet thermal spray layer which has magnetism, an excellent corrosion resistance and an excellent wear resistance, and to which a fusion treatment can be performed at a relatively low temperature to improve adhesion with a base material.SOLUTION: A powder for forming thermal spray layer, which is used for forming a thermal spray layer including a Mo(Ni, Cr, V, Fe)Btype compound boride, has a composition of B: 5.5-6.5 wt.%, Mo: 48.8-57.7 wt.%, i: 1.8-2.5 wt.%, Cr: 6.0-10.0 wt.%, V: 1.0-3.0 wt.%, Fe: 6.0-10.0 wt.%, and Ni: 17.0 wt.% or more.
