  • Patent number: 11028485
    Abstract: A method for marking an article may comprise forming a raised pad on a substrate of the existing article by applying a material to a surface of the substrate using a material addition process, and forming a design on a surface of the raised pad. The raised pad may be formed on the surface of the substrate to prevent mechanical stress from being propagated from the raised pad to the substrate in response to the design being formed on the raised pad.

  • Patent number: 10814580
    Abstract: A gas turbine engine includes an airfoil having a core that has a first hardness and a surface on the core. The surface includes a plurality of geometric features that have a second, greater hardness. The geometric features define a surface porosity by area percent and a corresponding surface solidity by area percent. The surface includes a ratio of the surface solidity divided by the surface porosity that is 1.8 or greater. The geometric features and the ratio establish the surface to be hydrophobic, and the second, greater hardness and the ratio establish an erosion rate of the surface that is equal to or less than an erosion rate of the core under identical erosion conditions.

  • Patent number: 10702939
    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.

  • Patent number: 10647065
    Abstract: A method of making a composite article involves first forming an intermediate substrate. The intermediate substrate can be formed from fibers and an uncured thermoset polymer composition followed by partial cure, or from fibers and an uncured thermoset polymer composition followed by cure of the thermoset polymer composition and deposition of a thermoplastic on the surface of the substrate, or from fibers and an uncured thermoset polymer composition followed by cure and exposure of the substrate to organic solvent, a plasticizer, moisture, and/or heat. The intermediate substrate prepared according to any of the above techniques is then subjected to cold gas spray deposition to deposit a metal layer onto the intermediate substrate. In the case where the substrate was formed by partially curing a thermoset polymer composition, the metal-coated partially-cured thermoset polymer substrate is then fully cured.
