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:
The invention relates to lubricants used in friction assemblies: rolling-element and slide bearings, hinged bearings, threaded joints, cogged and other gears under maximum temperatures up to 200-250 DEG . The proposed middle-temperature grease based on soap-thickened oils contains an organophosphoric additive, graphite and molybdenum disulphide. As an organophosphoric additive it contains a mixture of isomers - a product of the interaction between diethyl phosphite and N-arylsulphonylquinonimine, and as soap-thickened oils - a mixture of Ca-stearate or Li-12-hydroxystearate with heavy petroleum oils (MC20 oil). The proposed grease is far superior to known greases in terms of operating characteristics: anti-wear and anti-scuff properties under severe operating conditions, as well the grease having the property of increased retention time on friction surfaces. Under conditions of high temperature, ingress of water and slag, friction assemblies, bearings in particular, with the grease applied, operate for 200 twenty-four-hour periods and more.

A multi-purpose thread compound comprises, dispersed in a supporting vehicle, an extreme pressure agent, and particulate material comprising graphite and a calcium and/or magnesium inorganic salt, wherein substantially all the particulate material in the composition has a particle size of no greater than 50 mu m.
Abstract:
The disclosure relates to temporary corrosion resistant coatings and films upon metal substrates, e.g., metal tools and dies. The temporary coatings and films will not adversely chemically alter the surface of the underlying substrate. The coatings/films comprise a mixture of at least one of an acrylic, water, an oil, silica, at least one silicate, surfactants and optionally one or more buffering materials and waxes.
Abstract:
Processes for working of refractory metals and other metals employing a lubricant comprising perfluorocarbon compounds (PFCs), including aliphatic perfluorocarbon compounds ( alpha -PFCs) having the general formula: CnF2n+2, perfluoromorpholines having the general formula: CnF2n+1ON, perfluoroamines (PFAs) and highly fluorinated amines (HFAs), and perfluoroethers (PFEs) and highly fluorinated ethers (HFEs), and their polymerization products.

Abstract:
There are disclosed improved water-soluble metal working fluids comprising polyaspartic acid, amides and salts thereof, a corrosion inhibitor(s) and a basic additive said additive having sufficient basicity and buffering power to maintain the pH of the composition above about 8.5 and preferably above about 9. Such compositions are useful as lubricants in processes to cut, bend, grind and shape both ferrous and non-ferrous metals and tend to maintain higher pH values due to the incorporation of a basic additive. The polyaspartic acid and salts thereof are particularly advantageous in that the fluids can be easily disposed of after use without special treatment because polyaspartic acid and salts thereof are readily biodegradable.
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 composition to lubricate or preserve rubber materials having, by weight, 5-10 % graphite, 0.5-10 % of a titanate ester and the balance isopropyl alcohol. A rubber material is lubricated or preserved by the steps of applying such a composition to a rubber material and allowing the composition to adhere to the rubber material. The composition may also contain 0.5-5 % by weight of a fluorocarbon polymer and/or 0.02-5 % by weight of a UV stabilizer. The composition and method are particularly suited for lubricating and/or preserving rubber windshield wiper blades.
