Abstract:
A composition of matter for depositing a thin anti-friction film that has a coefficient of friction of 0.06 or less. The composition comprises (a) a mixture of solid lubricant particles, a thermoset resin, and a catalyst for setting the resin, and (b) an evaporative medium for carrying the mixture during deposition. A solid film lubricant system for protecting metal wear interfaces subject to high temperatures and wet lubrications, comprising an oil-attracting solid lubricant mixture with at least two elements selected from the group of graphite, MoS.sub.2 and BN; a support for the mixture to loads of at least 10 psi at temperatures of 600.degree.-800.degree. F. while being thermally stable; a thermally stable thermoset polymer matrix, the polymer having inherent hydrocarbon chemical attraction to form a tenacious oil film of the lubricating oil on the wearing surface. A method of making anti-friction coated surfaces comprising providing a light metal based cylinder surface; exposing nonoxidized metal of the surface; applying a high elastic modulus load-supporting metal layer onto at least portions of the light metal cylinder surface; and simultaneously distributing a solvent-based solid film lubricant mixture and thermoset polymer onto at least portions of the layer at about room temperature to form a coating of desired thickness.

Abstract:
A lubricant for the topical application to objects that will contact various forms of water, e.g., liquid, snow, ice, or mixtures thereof, to reduce friction and thereby increase speed, glide and maneuverability. The lubricant consists essentially of hexagonal boron nitride and a binder of single or mixed oxides or organics, the boron nitride content (after drying) being from about 36 wt. % to about 99 wt. %. Binders of particular interest are water-based colloidal aluminum oxide and colloidal silicon dioxide. This lubricant is suitable for topical applications in a thin layer to various sports objects, such as skis, snowboards, ice skates, snowmobiles, toboggans, sleds, boats, etc., where reduced friction, and thus higher speed, glide and maneuverability is desired. Although a solid stick form (by drying or pressure-less sintering) is preferred, the lubricant can be in the form of a paste or a powder. Further, this lubricant can be incorporated into waxes of the type previously used for friction reduction to obtain the benefit of both.
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.
