Coated metallic particles and process for producing same

摘要

Metallic coated particles are disclosed which comprise a core consisting essentially of a material selected from the group consisting of metals, metal alloys, ceramics, ceramic glasses, and a coating relatively uniformly distributed on the core. The coating consists essentially of a relatively ductile and/or malleable metallic material selected from the group consisting of metals and metal alloys. The process for producing the coated particles involves increasing the aspect ratio of the ductile and/or malleable material, and mechanically applying it to a powder material which is to be the core of the particles.
