US Patent 9796019 Powder metal with attached ceramic nanoparticles

A method for processing a powder material includes cleaning surfaces of a powder material that has spherical metal particles, coating the cleaned surfaces with an organic bonding agent, mixing the coated particles with a dispersion that contains ceramic nanoparticles, drying the mixture to remove a carrier of the dispersion and deposit the ceramic nanoparticles with a spaced-apart distribution onto the organic bonding agent on the surfaces of the particles, and thermally removing the organic bonding agent to attach the ceramic nanoparticles to the surface of the particles.
