Abstract:
An aqueous lubricant for use in plastic working of a metallic material which comprises (A) a water soluble inorganic salt, (B) a lubricating agent selected from molybdenum disulfide and graphite and (C) a wax, wherein the components are dissolved or dispersed in water, and wherein a solid concentration ratio (weight ratio) (B)/(A) is 1.0 to 5.0 and (C)/(A) is 0.1 to 1.0; and a method of lubricant film processing of a metallic material, characterized in that a lubricant film is formed by applying the aqueous lubricant in a dried weight of 0.5 to 40 g/m on a clarified metal material, followed by drying. The water soluble inorganic salt(A) is preferably selected from the group consisting of a sulfate, a silicate, a borate, a molybdate and a tungstate. The wax (C) is preferably a natural wax or a synthetic wax which is dispersed in water and has a melting point of 70 to 150 DEG . The aqueous lubricant can be used for imparting excellent bubricity with ease to the surface of a metal having no chemical film formed thereon.

Abstract:
A fluid bearing device which fills a conductive lubricant (6) containing an electrostatic charge preventive agent in a bearing clearance between a bearing sleeve (2) (sleeve 2) and bearing shaft (3) (shaft 3), and a magnetic disk device using this fluid bearing device. This configuration enables to continuously discharge static electricity charged in the shaft (3), a rotary part, to the sleeve (2), a fixed part, through the conductive lubricant (6). Accordingly, electrostatic charge is not built up in the shaft (3), which is the rotary part, even at high speed rotation.
Abstract:
This invention discloses novel catalyzed surface coating additives and catalyzed surface coating systems, which contain one or more catalysts, along with optional other ingredients, wherein the catalysts serve to effect in situ chemical bonding reactions in that the catalysts function to initiate, to promote, to accelerate, and/or to increase the formation and yield of persistent, solid, corrosion resistant, impact resistant, wear resistant, and/or non-stick surface coating films which may exhibit pigmentation and other aesthetic features, and may be designed to be environmentally benign.

This invention discloses novel catalyzed lubricant additives and catalyzed lubricant systems, which contain one or more catalysts, along with optional other additives, wherein the catalysts serve to accelerate the rate and increase the yield of the lubricant bonding reactions between the catalyzed lubricants and the wear surfaces being lubricated.
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. %.
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 members 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.
Abstract:
The disclosure pertains to a novel roller lubricant consisting of polyalkylene glycol, a thickening agent, one or more clay minerals and, optionally, graphite. The novel roller lubricant can be used to lubricate rollers used to produce profiled sections or sheets.
Abstract:
According to the method of the invention, first a paste is produced from a plastics dispersion and fillers in order to form the plastics sliding layer. This paste is free from organic solvents and is applied to a sintered porous metal layer. The resultant multi-layer material is then sintered. Since organic solvents are not used, the risks to health and the risk of fire are considerably reduced. Furthermore, the composite materials produced according to the invention have exceptional resistance to cavitation. In addition to conventional fields of application relative to lubrication-free articles, such as bearings, these composite materials can therefore also be used in gear pumps and shock absorbers.
Abstract:
Water-in-oil emulsions are disclosed that comprise: a) water; b) from about 10 to 65 % by weight of an oil; and c) an emulsification system comprising a polysiloxane polyalkyl polyether copolymer and a phthalic anhydride derivative, substantially permanently maintaining the water and oil as an emulsion, the emulsification system being substantially free from aluminum and zirconium salts, the emulsion being at a pH of from about 5 to 10.
Abstract:
A lubricant and surface conditioner for formed metal surfaces, particularly aluminum and tin beverage containers, reduces the coefficient of static friction of said metal surfaces and enables drying said metal surfaces at a lower temperature. The conditioner includes (i) a water-soluble organic material selected from amine oxides and quaternary ammonium salts, ethoxylated castor oil derivatives, and imidazoline moiety-containing phosphonates and preferably also includes (ii) at least one of fluozirconate, fluohafnate, or fluotitanate ion, and (iii) phosphate and/or nitrate ions. Good resistance to damaging the friction reducing effect by overheating and to staining of the domes of treated containers during pasteurization can be achieved.
