Abstract: 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.

Abstract: One embodiment includes a method for enhancing bond strength between a powder deposit and a substrate. Powder is deposited on the substrate. Powder is shot peened with peening media that is harder than both the powder and the substrate to produce bond strength between the powder and the substrate that is at least twice bond strength between the powder and the and peening material substrate without shot peening.
