  • Patent number: 5034187
    Abstract: A composition containing 30 to 70% chromium carbide, 5 to 20% soft noble metal, 5 to 20% metal fluorides, and 20 to 60% metal binder is used in a powdered metallurgy process for the production of self-lubricating components, such as bearings. The use of the material allows the self-lubricating bearing to maintain its low friction properties over an extended range of operating temperatures.
    Type: Grant
    Filed: August 23, 1990
    Date of Patent: July 23, 1991
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration
    Inventors: Harold E. Sliney, Christopher Dellacorte
  • Patent number: 4728448
    Abstract: A self-lubricating, friction and wear reducing composite material for use over a wide temperature spectrum from cryogenic temperature to about 900.degree. C. in a chemically reactive environment comprising silver, barium fluoride/calcium fluoride eutectic, and metal bonded chromium carbide.
    Type: Grant
    Filed: May 28, 1987
    Date of Patent: March 1, 1988
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration
    Inventor: Harold E. Sliney
  • Patent number: 4214905
    Abstract: A composite material is described which will provide low friction surfaces for materials in rolling or sliding contact and is self-lubricating and oxidation resistant up to and in excess of about 930.degree. C. The composite is comprised of a metal component which lends strength and elasticity to the structure, a fluoride salt component which provides lubrication and, lastly, a glass component which not only provides oxidation protection to the metal but may also enhance the lubrication qualities of the composite.
    Type: Grant
