  • Patent number: 11939646
    Abstract: Disclosed herein are embodiments of nickel-based alloys. The nickel-based alloys can be used as feedstock for PTA and laser cladding hardfacing processes, and can be manufactured into cored wires used to form hardfacing layers. The nickel-based alloys can have high corrosion resistance and large numbers of hard phases such as isolated hypereutectic hard phases.

  • Patent number: 11644106
    Abstract: A method of manufacturing a device includes thermally spraying tungsten carbine in feedstock that does not include Cobalt but that includes Nickel, Copper, or a Nickel-Copper alloy, the method improves the base coating toughness, anticorrosion, and antifouling properties for high load application in sea water and brackish water environments. Additionally, a Cobalt-free material lowers material costs and reduces the global demand of Cobalt. Providing a topcoat of a Silicon-doped DLC significantly reduces the topcoat brittleness of common DLC failures such as “egg shell” in high stress applications. Thus, high hardness, low friction applications may be tailored in high stress applications.

  • Patent number: 7763573
    Abstract: The production of solid lubricant agglomerates by combining solid lubricant powder, an inorganic binder, other fillers if optionally desired, and a liquid to form a mixture, and driving off the liquid to form dry agglomerates which are subsequently classified by size or milled and classified by size to yield agglomerates of a desired size range. These agglomerates are then treated to stabilize the binder, thereby strengthening the binder and rendering it nondispersible in the liquid. The treated agglomerates are then blended or clad with a metal, metal alloy or a metallic composition, to produce a composition suitable for thermal spray applications.
