| Abstract Scope |
Cold spray is a solid-state additive manufacturing technique that can achieve full density builds at speeds in excess of 10 kg/hr using metallic powder feedstocks. The cold spray process utilizes high-pressure spray gas to accelerated powder particles to velocities which allow for kinetic consolidation of the powder at temperatures well below the feedstock melting point. Due to its solid-state nature cold spray is well suited for deposition of refractory alloys, which become embrittled due to interstitial absorption when worked at higher temperatures. This work demonstrates rapid AM of near net shape tantalum using cold spray additive and investigates the properties of the tantalum after deposition including machinability, and mechanical strength. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. |
