    Abstract: A threaded joint for an oil well pipe is provided which prevents the occurrence of galling at the time of repeated tightening and loosening and which provides a high degree of air tightness and has excellent galling resistance and air tightness without using a liquid lubricant such as a compound grease. 1. A lubricating film of an inorganic polymeric compound which has an M (metal element)nullO (oxygen) backbone and has a solid lubricant dispersed therein is formed on a threaded portion or an unthreaded metal contact portion. 2. A phosphate film and the lubricating film of the inorganic polymeric compound is formed on the threaded portion or the unthreaded metal contact portion. 3. A Cu plating layer and the lubricating film of the inorganic polymeric compound or a lubricating film of a resin in which a solid lubricant is dispersed is formed on the threaded portion or the unthreaded metal contact portion. 4. A lubricating film of the inorganic polymeric compound or a lubricating film of the polymer and a rust preventing film containing an alkali metal salt of a carboxylic acid or an alkali earth metal salt of a carboxylic acid are formed on the threaded portion or the unthreaded metal contact portion.

    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.
