Abstract
Implementations provide gas atomized metal matrix composite ('GAMMC')-based feedstock for cold spray additive manufacturing (“CSAM”) enabling complex structural repairs. The feedstock is prepared by arranging a metal matrix composite (MMC) material in a gas atomization system, wherein the MMC material includes metal particles and ceramic particles. The feedstock is further prepared by performing gas atomization of the MMC material using the gas atomization system to atomize the MMC material, and producing a feedstock powder comprised of metal particles that are embedded with the ceramic particles from the atomized MMC material. The GAMMC-based feedstock comprises metallic (for binding to the substrate of the damaged part) and ceramic (for reinforcement) particles bonded together such that the ceramic particles bond directly to and within the metallic particles. GAMMC-based feedstock strengthens the repaired part and prevents degradation of the mechanical properties of the repaired part below stock specifications.
