    摘要: The present invention provides a transition metal/polymer matrix composite material which has durable, wear and corrosion resistant and friction reducing 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 transition metal dichalcogenide (TMDs) disulfides of tungsten and molybdenum, and the polymer polytetrafuoroethylene (PTFE). This invention brings together the unique properties of organic chemistry (PTFE) and inorganic chemistry (TMD's) and creates a synergistic interaction optimizing the friction reducing properties of PTFE with similar friction reducing properties of select TMD's, and, the TMD's additional wear-resistance and natural tendency for forming a tenacious physical bond at a molecular level. The invention comprises a mixture of PTFE and TMDs (particularly tungsten disulfide and molybdenum disulfide) which can be applied to a substrate through a variety of mechanisms and manners to form a lubricious and wear-resistant layer ranging from 0.5 micron to 60 microns thick.
