  • Patent number: 10493524
    Abstract: A method for processing a powder material includes feeding a powder material through an additive processing machine to deposit multiple layers of the powder material onto one another and using an energy beam to thermally fuse selected portions of the layers to one another with reference to data relating to a particular cross-section of an article being formed. The powder material has spherical metal particles and a spaced-apart distribution of ceramic nanoparticles attached to the surfaces of the particles. The ceramic nanoparticles form a dispersion of reinforcement through the formed article.

  • Patent number: 10495231
    Abstract: A disclosed method of hard coating a wear surface of a valve of an aircraft air management system is performed by depositing a hardface alloy powder onto the wear surface, heating the wear surface and the hardface alloy powder to transform the hardface alloy powder into a molten liquid mass, and subsequently cooling the molten liquid hardface alloy mass to solidify the hardface alloy onto the wear surface. The disclosed process provides for localized application and subsequent bonding of the hardface alloy to discrete portions of the wear surface. The solidified hardface alloy coating may then be machined to obtain specific wear surface geometries.

  • Patent number: 10407755
    Abstract: The method includes providing a powder that has heterogeneous particles with a ratio, by weight, of an amount of nickel to an amount of a metal. The ratio is selected in accordance with a compositional ratio that can substantially bear a nickel intermetallic precipitate of the nickel and the metal. The heterogeneous particles are then consolidated and thermally treated to interdiffuse the nickel and the metal. The interdiffused nickel and metal are then precipitation treated to precipitate the nickel intermetallic.

  • Patent number: 10272382
    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.
