大気中プラズマ溶射及び溶線式アーク溶射に使用される合金粒子及び線材

摘要

Problem to be Solved The present invention relates to improvement in alloy powder particles or wires used as a source material in atmospheric plasma spray and wire arc spray to reduce the amount of oxides on the thermal-sprayed coating. Solution The alloy particles and the wire of the present invention 1 are doped with at least an element to be oxidized and evaporated preferentially as compared to the major alloy elements on the particle surface during flight by spraying.
