The actual mechanism by which the solid particles deform and bond duffing cold spray is still not well understood. For example, High-strength brass powder was little deposited in spite of low melting temperature. In this study, it was aimed to clear the deposition behavior with investigation of critical velocity with numerical simulation and observation of an individual particle. Although deposition efficiency is different, copper: 80%, 60/40 brass: 60% and High-strength brass: almost 0%, critical velocity is almost equal. High-strength brass powder were done brittle fracture. From these results obtained, it seemed that low deposit efficiency cause of brittle β-phase.
