ABSTRACT:
A boron-containing nickel or cobalt spray-and-fuse self-fluxing alloy powder contains hard precipitates of chromium boride and, optionally, chromium carbide which are internally precipitated from a melt of said alloy. Such alloy powder is made by atomizing the melt at about the temperature at which the melt is viscous.
