    摘要: 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.

    摘要: A lubricant composition comprises a perfluorinated polyalkylether base fluid (PFPAE) and an oxidation-corrosion inhibiting amount of a perfluoro-substituted benzothiazole or bis-benzothiazole. The benzothiazole compound additive exhibits excellent solubility in the base fluid and possesses outstanding low volatility characteristics. As a result, the lubricant composition functions as a noncorrosive, stable material suitable for long term applications over a wide temperature range (-65.degree. F. to >600.degree. F.) in an oxidative environment.The perfluoro-substituted benzothiazoles and bis-benzothiazoles have the formula: Q--R.sub.f or Q--R.sub.f '--Q, wherein Q is ##STR1## wherein R.sub.f is a linear or branched perfluoroalkylether group containing at least one ether linkage and R.sub.f ' is a linear or branched perfluoroalkyleneeher group containing at least one ether linkage.In formulating the lubricant composition of this invention, an oxidation-corrosion inhibiting amount of the substituted benzothiazole is dissolved in the PFPAE base fluid. The amount of the benzothiazole employed generally ranges from about 0.05 to 5.0 weight percent, preferably about 0.5 to 2.0 weight percent, based on the weight of the base fluid. This provides a lubricant containing an amount of oxidation-corrosion inhibiting additive that is adequate for long term applications at elevated temperatures while maintaining excellent formulation stability after storage at low temperatures for long periods of time.
