  • CVD method of forming self-lubricating composites
    Patent number: 5843533
    Abstract: An article having a multiphase composite lubricant coating of a hard refractory matrix phase of titanium nitride dispersed with particles of a solid lubricating phase of molybdenum disulfide is prepared by heating the article to temperatures between 350.degree. and 850.degree. C. in a reaction vessel at a reduced pressure and passing a gaseous mixture of Ti((CH.sub.3).sub.2 N).sub.4, MoF.sub.6, H.sub.2 S and NH.sub.3 over the heated article forming a multiphase composite lubricant coating on the article.
    Type: Grant
    Filed: September 29, 1995
    Date of Patent: December 1, 1998
    Assignee: Lockheed Martin Energy Systems, Inc.
    Inventors: Theodore M. Besmann, Peter J. Blau, Woo Y. Lee, Yong W. Bae
