Abstract
In the process of forming metal powders by rotary atomization, the atomizer disk is first coated with a stable compound of the molten metal to be poured or, if the metal to be poured is an alloy, the disk is coated with a compound of the base metal of the alloy. The coating compound is selected on the basis of its melting point and that it can coexist with the molten metal to be poured, at the pour temperature, as indicated by phase diagrams of the materials involved. The molten metal is poured onto the coated, spinning disk, couples with the coating, and forms a stable skull of itself over the coating. Fine droplets of molten metal are thereafter flung from the disk, cooled and collected.
