Abstract:
A lubricant coating disposed between a substrate and a counter surface comprises a reaction layer immediately adjacent the substrate. A bonding layer is immediately adjacent the reaction layer, with the bonding layer comprising a first composition. A low friction, lubricious layer is immediately adjacent the bonding layer, with the lubricious layer comprising a second composition that is different from the first composition.
Abstract:
The invention concerns a composition for preparing metal products designed to be shaped by at least one mechanical process of plastic deformation such as wire drawing, rolling, calendering, forging, swaging and the like, without notable shrinkage of substance. The invention is characterised in that it comprises a film-forming binder, at least an additive reactive with the metal, at least a lubricating additive and at least an anticorrosive additive. The invention also concerns a method for preparing said metal products using the claimed composition.

Abstract:
In cold flow processing of metals, especially steel, coatings of transition metal halogenides, especially FeCl3, have proved suitable because they efficiently counteract cold welding problems. The coatings may be applied in the form of a melt or a saturated or diluted, aqueous solution of the transition metal halogenide. If a melt is used, it may be mixed with one or more common solid lubricants such as MoS2, graphite, or the like.
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 C3-6 polyhydric alcohols, polyvinyl esters, and polyvinyl pyrrolidones. The binder is solubilized in an organic solvent.
Abstract:
A solid lubricant additive for resin-bound friction lining mixtures is characterised in that it contains a combination of copper-I-sulphide (Cu2S) with at least another sulphide of molybdenum, zinc, antimony, wolfram, tin and/or titanium.
Abstract:
A rubber or plastic sliding member coated with a material having excellent durability and high slipperiness, wherein the coating material is composed of a solid lubricant such as molybdenum disulfide and a resin matrix comprising a fluoroolefin vinyl ether polymer resin and/or a fluoroolefin vinyl ether/vinyl ester copolymer resin.
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:
