  • Layered coating and method for forming the same
    Patent number: 8092922
    Abstract: A layered coating is disclosed herein. The layered coating includes a chromium layer, an intermediate layer of chromium and nitrogen established on the chromium layer, and an outer layer of chromium and nitrogen established on the intermediate layer. The intermediate layer has a gradually changing composition, wherein the chromium concentration decreases from an area of the intermediate layer adjacent the chromium layer towards a surface of the layered coating.
    Type: Grant
    Filed: June 30, 2008
    Date of Patent: January 10, 2012
    Assignee: GM Global Technology Operations LLC
    Inventors: Leonid C. Lev, Michael J. Lukitsch, Yang T. Cheng, Anita M. Weiner, Robert F. Paluch, Neil E. Anderson

  • Gear surface treatment procedure
    Patent number: 7138066
    Abstract: A method of surface treating heat treated members to remove oxide scale. The heat treated members are subjected to a staged series of discrete chemical and physical cleaning steps yielding a substantially scale-free surface readily adaptable for subsequent application of protective coatings.

  • Planetary gearset with multi-layer coated sun gear
    Patent number: 6846261
    Abstract: A planetary gearset includes a sun gear member having a sun gear body made of a steel material and an outer periphery with a plurality of teeth formed thereon. Each of the sun gear teeth has at least one mating surface for engaging mating surfaces on complementary teeth on at least one planet gear. A fatigue-resistant coating is applied to the mating surfaces of the sun gear teeth. The coating is harder and more abrasive than the mating surfaces of the planet gear teeth.

  • Electroplated Ag-Ni-C electrical contacts
    Patent number: 5967860
    Abstract: Nesting electrical connectors comprising a substrate and a silver-nickel-carbon electrodeposit atop the substrate. The electrodeposit is at least about 0.5 micrometers thick, and comprises about 10 to about 25 atomic percent nickel which is dispersed as a discontinuous phase throughout a continuous phase of the silver and has a Scherrer grain size less than about 5 nanometers. The carbon comprises about 5 to about 15 atomic percent of the deposit and has a non-crystalline graphite structure.
