Abstract: Embodiments of the present invention may provide textured surfaces to be lubricated, the texturing to enhance the effectiveness of the intended nano-lubrication. The texturing may make asperities and depressions in the surface to be lubricated. This texturing may be executed, for example, by chemical etching, laser etching, or other techniques. This texturing may create locations in the lubricated surface to hold or anchor the intended nano-lubricants, to facilitate the creation of a tribo-film on the surface when the lubricated surface is used under pressure, and resulting in delivery of multiple chemistries from the nano-lubricant.
Abstract: 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 composition of matter for use in tribological applications, such as in mechanical seals, bearings and other sliding or rubbing components, which provides good durability and wear characteristics. The material is used in the "softer" one of two relatively sliding members which are in, or may come into, contact with each other during the relative rotation of one of the member s relative to the other. The material is a carbon or carbonaceous formed material, such as is normally used in the manufacture of a primary seal ring in a mechanical seal, and comprises an additive compound which contains at least one compound from a group consisting of neodymium fluoride, praseodymium fluoride, gadolinium fluoride and lanthanum fluoride.
