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.
Abstract:
A solid lubricant additive for resin-bound friction lining mixtures contains manganous sulphide (MnS). The additive further optionally contains other sulphides, carbon carriers such as graphite and coke, phosphates and/or oxides. The additive results in the adjustment of the coefficient of friction and wear in friction lining materials. The additive may be advantageously employed in asbestos-free and lead-free friction lining mixtures in heavy-duty friction parts as used in brakes, clutches, synchromesh gears.
Abstract:
Lubricant for use in hot forming of steel at high temperatures and especially in the production of seamless tubes in so-called multiple pipe mills, in which the lubricant must adhere water-resistant to the tool. This is achieved by a lubricant containing, besides a solid lubricant and a thickening agent, a binding agent from the series of the carboxylated styrene-butadiene latices.
Abstract:
A grease composition comprises a base oil and a particular amount of at least one intercalation compound consisting of a metal phosphorus chalcogenide as a host and an alkylamine or alkylammonium chloride as a guest, and has excellent extreme pressure property and wear resistance.
Abstract:
Compositions for coating steel wire to facilitate the cold drawing thereof comprising:A. from about 50 to about 99.9% by weight of K.sub.2 SO.sub.4 ;B. from about 0 to about 49.99% by weight of K.sub.2 B.sub.4 O.sub.7 and/or KBO.sub.2 ; andC. from about 0.01 to about 5% by weight of an ammonium and/or a potassium soap; wherein up to 50% by weight of the total potassium plus ammonium ions in the composition can be replaced by sodium ions. These compositions form coatings which have good crystalline structure and drawability with low hygroscopicity.

Abstract:
A composition for surface treatment of firearms and bullets provide a corrosion resistance and dry lubrication. It comprises an admixture of finely divided molybdenum disulfide and sodium molybdate in an organic solvent.
Abstract:
A lubricant additive that includes antimony thioantimonate and antimony trioxide in a specified ratio for enhancing the extreme pressure, antiwear, and antiabrasive properties of conventional lubricants as well as for use in lubrication of a wide variety of lubricated contact surfaces.
Abstract:
The present invention includes a method for the manufacture of a bearing seal which includes providing a polymer and/or a filler coated with a polymer and thereafter heating the coated filler to bond the copolymer to the filler. Following cooling of the coated filler, it is pulverized and added to granular polytetrafluoroethylene. This admixture is then mixed to obtain a uniform blend and thereafter shaped by compacting and heating into a preselected form. Fillers suitable for the present invention may be carbon, metal, glass, carbide, disulfide, polymeric, polyester fluoride and ceramic fibers.
Abstract:
Improved composite bearings are provided employing cold forming and sintering techniques. Improvements in compositions for impregnating porous layers of composite bearings are provided comprising lead or lead alloy, perfluorinated polymer, particulate thermoplastic polymer and clay in particular proportions. When such materials are formed into bearings and subsequently sintered, improved resistance to stripping and wear is provided.
Abstract:
A part is made of a material comprising less than 90% by weight of a polymer selected from the group consisting of polytetrafluoroethylene, polyurethane, nitrile, fluoroelastomer, and polyphenylene sulfide; and more than 10% by weight of another material, comprising about 15% to 60% by volume of grains of titanium carbide dispersed through a metal matrix.
