Abstract:
A rheologically controlled glass lubricant for hot metal working comprises a glass powder, a binder, a rheological agent, and a weetting and viscosity modifier. These materials may be dispersed in a carrier. The lubricant is made by mixing the constituent elements, milling the mixture, and stabilizing the milled mixture. The lubricant can be used in a forging operation by coating a metal part with the lubricant, heating the coated part, placing the coated heated part in a forge, and rapidly applying sufficient pressure to deform the coated metal part into a desired shape.
Abstract:
Composite bearings 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:
Die Erfindung beschreibt eine Vorrichtung mit einem evakuierbaren Hohlraum der von einem Gehäuse umschlossen ist, wobei in dem Hohlraum und/oder an dem Gehäuse und in den Hohlraum hineinragend zumindest eine Reibbaugruppe und/oder Lagerbaugruppe angeordnet ist, die zumindest zwei Elemente mit je einer Oberfläche aufweist, wobei die beiden Oberflächen zusammenwirken und zumindest eine der beiden Oberflächen mit einem Gleitlack zumindest im Bereich des Zusammenwirkens beschichtet ist, der ein polymeres Bindemittel sowie Molybdändisulfid (MoS 2 ) und Graphit als Festschmierstoffe umfasst. Des Weiteren beschreibt die Erfindung eine Antifriktionspaste, eine Antifriktionsdispersion sowie die Verwendung eines Gleitlackes unter Hoch- bzw. Ultrahochvakuum.
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.
