Coated metallic powder and method of making the same

摘要

A metallic powder is disclosed. The metallic powder includes a plurality of metallic powder particles. Each powder particle includes a particle core. The particle core includes a core material comprising Mg, Al, Zn or Mn, or a combination thereof, having a melting temperature (T). Each powder particle also includes a metallic coating layer disposed on the particle core. The metallic coating layer includes a metallic coating material having a melting temperature (T). The powder particles are configured for solid-state sintering to one another at a predetermined sintering temperature (T), and T is less than T and T.
