  • Hybrid series transition metal polymer composite sets
    Patent number: 5565417
    Abstract: The present invention provides a specific hybrid series of transition metal polymer matrix composite sets which create durable friction reducing, wear, and corrosion resistance characteristics which can be used in a powder or liquid form, or, which can be bonded to a desired surface at ambient temperature. The specific components are combinations of polytetrafluoroethylene and molybdenum disulfide, polytetrafluoroethylene and tungsten disulfide, or tungsten disulfide and molybdenum disulfide. This invention brings together the unique properties of organic chemistry (polytetrafluoroethylene) and inorganic chemistry (tungsten disulfide, or molybdenum disulfide). This invention creates a synergistic interaction which enhances the wear resistance properties of polytetrafluoroethylene while simultaneously improving the friction reducing properties of molybdenum disulfide, or tungsten disulfide.
