COLD SPRAY NOZZLES

摘要

A nozzle assembly (100) for a cold spray deposition system (10) includes a nozzle body (102) with an axial bore. The axial bore defines a converging segment (112), a diverging segment (116) downstream of the converging segment (112), and a throat (114) fluidly connected between the converging and diverging segments (112, 116) of the axial bore. A particulate conduit (108) is fixed within the axial bore and extends along the axial bore diverging segment (116) for issuing solid particulate into the diverging segment (116) of the axial bore .
