ABSTRACT:
Methods for manufacturing compressible and sinterable metal powders are provided by this invention which include contacting core metal particles with a sol of a precursor of a metal. The sol has a viscosity of from about 10-10.sup.5 centipoise and comprises at least 1.0 weight percent of the precursor in a liquid medium. The final coating is produced by removing the liquid from the sol and then converting the precursor to form a substantially uniform layer of a Cu-Ni-Mo alloy on the surfaces of the soft iron or steel core metal particles.
