Abstract

Nickel-aluminum alloys containing boron in powder form are disclosed. These alloys are subjected to melt-spinning to form a brittle filament consisting in large measure of a metastable solid solution phase. This is then pulverized to powder configuration. Such powders exhibit excellent sprayability to form a dense, homogeneous, hard coating on a metallic substrate. The alloys, also exhibit excellent resistance to high temperature oxidation.
