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.
Abstract:
A reversible thermal thickening grease for microelectronic packages, in which the grease contains filler particles; at least one polymer; and a binder; in which the filler particles are dispersed within the binder, in which one or more segments of the at least one polymer may be attached to the filler particles prior to dispersion in the binder, and in which the polymer collapses at temperatures below a Theta temperature and swells at temperatures above a Theta temperature. During the operation of a microelectronic package, grease pump-out and air proliferation are minimized with use of the reversible thermal thickening grease, while grease fluidity is retained under repetitive thermal stresses.
Abstract:
There is provided a lubricant composition which includes: a first particle having a spherical shape having a diameter of 1 to 300 nm, having a Moose Hardness of 5 or more, at an amount of 0.01 to 40 weight %; and a second particle, having a diameter of 500 nm to 50 μm, having a brinel hardness of 17HB or less, at an amount of 0.01 to 40 weight %. The lubricant composition can form a bearing structure when the lubricant composition is subjected to an extreme pressure. The second particles are deformed into a retainer for the first particle.

Abstract:
The present invention relates to an anti-friction and anti-wear liquid coating composition for use with parts made of materials that have softening points below about 300null F. and articles so coated. The present invention also relates to a method of coating parts made from a low softening point materials with an anti-friction and anti-wear hard coating composition. The coating composition comprises a mixture of (i) solid lubricants comprising boron nitride, graphite and molybdenum disulfide, (ii) a thermoset resin system, (iii) catalyst for curing the resin system and (iv) a solvent system comprising highly volatile solvents. The coating composition is applied to the part and cured to form a coating on the part.
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:
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.
