Abstract: A nozzle for a cold spray deposition apparatus includes a convergent section defined about a nozzle inlet, a divergent section defined about a nozzle outlet, and a surface treatment that projects from an exterior of the divergent section, where an interior of the divergent section conveys a powder material received from the convergent section.

Abstract: Aspects include supplying a plurality of nickel-enriched braze powder particles to a cold spray system through a particle supply inlet. The nickel-enriched braze powder particles are accelerated through a transfer tube and out an exit in the transfer tube towards a substrate to produce a braze cold-sprayed substrate. A component surface is positioned proximate to the braze cold-sprayed substrate. The braze cold-sprayed substrate is heated to bond the braze cold-sprayed substrate to the component surface.

Abstract: An adapter for connecting a cold-spray nozzle to a cold-spray machine includes a receiver having a first end and a second end and defining an internal space for receiving the cold-spray nozzle; an end cap engageable with the first end of the receiver for securing the cold-spray nozzle in the receiver and having an opening aligned with an outlet of the cold-spray nozzle; and a threaded connection at the second end of the receiver, the threaded connection being configured for connection to the cold-spray machine.

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.

Abstract: A fluidized powder heat treatment classification assembly includes a gas source. A fluidized bed is connected to the gas source via a metered connection. The fluidized bed includes a first output connected to a powder classifier via at least a first valve. The powder classifier includes a catch container operable to decelerate a gas flow from the output and operable to catch particles entrained in the gas flow.

Abstract: A method for cold spray deposition of a material on a substrate, comprising the steps of entraining a metal powder material in a stream of accelerant gas comprising hydrogen; forming a flow of shield gas around the stream of accelerant gas; and impacting the substrate with the stream of accelerant gas whereby the metal powder material is deposited on the substrate.
