CERMET COVERING MATERIAL, ALLOY POWDER FOR MANUFACTURING CERMET COVERING MATERIAL, AND METHOD FOR MANUFACTURING CERMET COVERING MATERIAL

摘要

Provided is a cermet covering material obtained by covering a substrate with a cermet layer, wherein the cermet covering material is characterized in that the cermet layer contains 30 to 80 percent by mass of a hard phase including a compound boride of Mo2(Ni,Cr)B2, the remainder comprising a binding phase of an Ni group alloy having a crystallinity of 15% or more. According to the present invention, it is possible to provide a cermet covering material having a film covering exhibiting excellent corrosion resistance and wear resistance, while experiencing a minimal degradation in characteristics even when exposed to high temperatures.
