We have studied properties of the coating using grinded scraps of hard metal by the high velocity flame spray method. It was possible to make scraps thermal spray powders which was reduced at 1073K, and graphite was added so that the total content become 6mass%, and then presintered at 1473K in hydrogen. The coating using the scraps was similar to the coating using commercial powders in the microstructure and hardness of the coating. But the wear rate of the coating using the scraps was three times larger than the coating using commercial powders. This is considered to mainly result from the increase of the roughness of coating surface due to ununiformity of the particle size of the scraps.
