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:
The present invention provides a new composite material comprising a porous matrix made of metal, metal alloy or semiconducting material and hollow fullerene-like nanoparticles of a metal chalcogenide compound or mixture of such compounds. The composite material is characterized by having a porosity between about 10 % and about 40 %. The amount of the hallow nanoparticles in the composite material is 1-20 wt.%.
Abstract:
Dry film lubricant coatings are provided by using a silicone resin binder, either as an aqueous emulsion or in a solvent-based system, to fix an alkaline earth metal fluoride to a substrate. The compositions used to apply the coatings may also include relatively minor amounts of xylene, ammonium benzoate, a wetting agent, and/or a porosity-inducing agent - although none of those additives remains in the cured coating. Multi-layer dry film lubricant coatings are also disclosed, with the multi-layer coating having a basecoat layer as described above, and a topcoat layer made of a layer-lattice solid such as graphite or molybdenum disulfide, and a silicone resin, aluminum phosphate or an alkali metal silicate binder.
Abstract:
The invention relates to a lubricant which can be used as a mandrel lubricant with a content of 75 to 90 wt. % of graphite and contains 1 to 10 wt. % of a phosphate. Said lubricant can also contain 1 to 4 wt % alkali silicate, 1 to 10 wt. % bentonite, 0.5 to 1 wt. % silico-phosphate and common solid lubricants. Said lubricant is preferably used as an aqueous suspension with a solid content of 20 to 40 wt. %.
