  • Bearing members having coated wear surfaces
    Patent number: 3936295
    Abstract: The invention comprises bearing members having a coated wear surface applied by plasma-spraying an aggregate of particles thereon consisting of nickel-aluminum particles, nickel-molybdenum particles, tungsten carbide particles, and intermetallic alloy particles to form a high temperature, oxidation resistant, wear resistant, and scuff resistant coating. Alloying of the constituents in the final coating is desired and is achieved by encapsulating both the aluminum and molybdenum particles with nickel (alternatively the nickel-aluminum may be in the form of a bonded aggregate), by sintering the tungsten carbide in a matrix of cobalt, and by alloying nickel-cobalt, carbon, silicon, chromium, boron, and iron into an intermetallic alloy to form an aggregate of four types of particles for plasma-spraying onto the wear surface.
