Abstract
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. The material functionality of this invention is greatly improved over the individual friction-reducing and wear-resistance capabilities of its constituent components being use independently. The invention comprises varying mixture sets of polytetrafluoroethylene and molybdenum disulfide, polytetrafluoroethylene and tungsten disulfide, or molybdenum disulfide and tungsten disulfide, depending upon the desired friction and wear-resistance needed. This invention can be introduced into the lubrication of mechanical components in powder form, in a colloidal dispersion, or, can be applied and caused to bond directly to a substrate surface through a variety of mechanisms and manners to form a lubricious and wear-resistant layer ranging from 0.5 microns to 60 microns thick.
