Abstract: A nozzle assembly for a cold spray deposition system includes a nozzle body with an axial bore. The axial bore defines a converging segment, a diverging segment downstream of the converging segment, and a throat fluidly connected between the converging and diverging segments of the axial bore. A particulate conduit is fixed within the axial bore and extends along the axial bore diverging segment for issuing solid particulate into the diverging segment of the axial bore.

Abstract: A carrier gas recovery system for use in cold spray manufacturing recovers carrier gas utilized during the cold spray process and recycles the carrier gas for immediate use or stores the carrier gas for future use. The carrier gas recovery system includes an enclosure subsystem, a filtration subsystem, a reclamation subsystem, and a compensation subsystem. An article is placed in the enclosure and particulate matter is carried to the article on a carrier gas stream. Carrier gas in the enclosure is filtered through the filtration subsystem to remove particulate from the carrier gas, and the filtered carrier gas is fed to the reclamation subsystem. The carrier gas either flows to a gas separator, to increase the concentration of carrier gas, or to the compensation subsystem if the carrier gas concentration is sufficiently high. The carrier gas can be stored in the compensation subsystem or used in further cold spray manufacturing.
