Abstract: Implementations provide cold spray additive manufacturing (“CSAM”) with gas recovery in situ in an open environment without requiring part disassembly and removal to a repair facility. Recapturing and reusing gas in an open environment reduces costs, rendering CSAM more commercially viable and efficient, and avoids risk of new damage to parts from contemporary pre-existing CSAM processes. A gas recovery nozzle attaches to a supersonic nozzle and sends used gas to a gas recovery sub-system by capturing gas that is deflected on impact with the part during CSAM. Captured gas is stored for reuse. A flexible coupling controls distance from the gas recovery nozzle to a part substrate to prevent (1) nozzle clogging; (2) stationary shock wave interference with gas flow; and (3) gas flow misdirection. The gas recovery nozzle also suppresses disruptive supersonic sounds. Implementations enable capture for later reuse of supersonically-propelled gas during in-situ CSAM in open environments.
