Abstract:
A solid lubricant and composition useful for lubricating the flanges of locomotive wheels, railcar wheels, rail track and in applications where it is desirable to reduce friction when metal contacts metal. The solid lubricant having from about twenty-five percent to about seventy percent by volume of a polymeric carrier, about five to seventy-five percent by volume of organic and inorganic extreme pressure additives, about zero to twenty percent by volume synthetic extreme pressure anti-wear liquid oil, and about zero to one percent by volume optical brightener.

A solid lubricant and composition useful for lubricating the flanges of locomotive wheels, railcar wheels, rail tracks and in applications where it is desirable to reduce friction when metal contacts metal. The solid lubricant having from about 25% to about 70% by volume of a biopolymer polymeric carrier, about 5% to 75% percent by volume of organic and inorganic extreme pressure additives, about 0% to 20% by volume synthetic extreme pressure anti-wear liquid oil, and about 0% to 1% by volume optical brightener.

Abstract:
A body of anti-friction material with reduced wear is formed of at least one carbon filling and a binder matrix of synthetic resin. The body of anti-friction material contains a phosphate, especially a phosphate of di- or pyrophosphoric acid, which is fixed in fine pulverized form in the binder matrix.
Abstract:
A low friction cam shaft for actuating at least one valve of an internal combustion engine includes a shaft member extending longitudinally, at least one cam secured to the shaft member, the cam being made of a plurality of density metal materials and having an outer surface impregnated with a solid film lubricant that has an affinity for oil and promotes rapid formation of a stable oil film to reduce friction therebetween.
Abstract:
A resin composition for a sliding part comprising 5 to 45% by volume of a carbon fiber, 1 to 25 by volume of a metal powder and a remaining amount of a melt-processable fluorine-containing resin. A molded article made of the composition has a low friction coefficient having a narrow fluctuation range and has an excellent abrasion resistance to a soft metal.
Abstract:
The present invention provides lubricant compositions for the powder metallurgical field. The lubricant compositions contain a solid phase lubricant such as graphite, molybdenum disulfide, and polytetrafluoroethylene in combination with a liquid phase lubricant that is a binder for the solid phase lubricant. The binder can be chosen from various classes of compounds including polyethylene glycols, polyethylene glycol esters, partial esters of C.sub.3-6 polyhydric alcohols, polyvinyl esters, and polyvinyl pyrrolidones. The binder is solubilized in an organic solvent.
Abstract:
A lubricant composition useful for hot plastic working of metal material comprises 100 parts by weight of graphite particles and 2 to 100 parts by weight of particles of at least one metal oxide selected from oxides of Sn, Pb, Zn, Ca, Cu and Al and having an average size of 0.01 to 20.0 .mu.m.
Abstract:
A method for treating the phosphate sludge waste from phosphate conversion baths used in the metal forming and metal working industry is described whereby the phosphate sludge is completely converted into a lubricant additive which can be used in lubricant formulations for the metal forming and metal working industry as well as general purpose lubricants. By operation of this process, waste treatment and waste disposal problems associated with the phosphate sludge are essentially eliminated. Various dry-soap lubricant formulations, warm forming lubricant formulations, non-reactive lubricant formulations, and metal precoat formulations containing the recovered or recycled phosphate sludge additive are described. The lime normally contained in many of these lubricant formulations can be significantly reduced or essentially eliminated by using the recovered phosphate sludge additive of this invention, thereby resulting in improved lubricant formulations. The recovered phosphate sludge is especially useful as an Extreme Pressure Additive.
Abstract:
Thin impermeable, corrosion-resistant, durable, dry lubricant coatings are provided as well as coated products and methods for the production thereof. The coatings comprise solutions of sulfur-containing metallic compounds and fluorocarbon polymers dissolved in mineral oil solvents and are applied to surfaces of substrates such as metallic surfaces.
