Abstract:
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 dichalcogenides (TMDs) including disulfides, diselenides and ditellurides of Ti, Zr, Hf, V, Nb, Cr, Mo, and W, and polymers including polytetrafuoroethylene (PTFE), hexafluoropropylene, perfluoroalkoxyvinyl ether, ethylenetetrafluoroethylene polymer, polyvinylidene fluoride and ethylenechlorotrifluoroethylene polymer. This invention brings together the unique properties of organic chemistry (PTFE) and inorganic chemistry (TMD's) which 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.

Abstract:
A wire rod is payed out from a pay-off stand and descaled in a descaling process. After preheating to a predetermined temperature by a preheating device, it is subjected to a lubrication pretreatment through a zinc calcium phosphate solution applied with ultrasonic wave in the lubrication pretreatment process. After rinsing process, the lubrication-pretreated wire rod is coated with a calcium stearate or a sodium stearate in lubricating process. Thereafter, the wire rod is dried sufficiently in drying process, and then added with a predies lubricant in wire drawing process and coiled by a coiler.
