Abstract:
A method of coating uses an anti-seizure agent for hot steel working that exhibits excellent wettability and surface film-adherability. The agent comprises: an inorganic component (first component); sodium hydroxide (second component); water-soluble resins and/or water-soluble surfactants (third component); and water. With the sum of the first component, the second component, and the third component as 100 mass %, the anti-seizure agent contains: 96.5 mass % or more and 99.98 mass % or less of the first component; 0.01 mass % or more and 2.0 mass % or less of the second component; and 0.01 mass % or more and 1.5 mass % or less of the third component, and the inorganic component is one or more selected from a group consisting of Al2O3, SiO2, CaO, B2O3, K2O, and Na2O. A coating layer formed solidly adheres to the steel and does not come off in both cold and hot working.

Provided herein are compositions that include an aqueous-based insulating fluid that comprises an aqueous base fluid, a water-miscible organic liquid, and a synthetic polymer. In another embodiment, provided herein is a method of forming an aqueous-based insulating fluid comprising: mixing an aqueous base fluid and a water-miscible organic liquid to form a mixture; adding at least one synthetic polymer to the mixture; allowing the polymer to hydrate; optionally adding a crosslinking agent to the mixture comprising the synthetic polymer to crosslink the synthetic polymer; placing the mixture comprising the synthetic polymer in a chosen location; allowing the mixture comprising the synthetic polymer to activate to form a gel therein.
Abstract:
A grease composition for construction equipment comprises a lubricating grease, a) 1 to 5% by weight of phosphate glass and b) 1 to 5% by weight of a sulfur-phosphorus extreme-pressure additive; as well as c) 0.5 to 3% by weight of an aromatic sulfonic acid salt and d) 0.1 to 3% by weight of a triazole compound as optional components based on the total weight of the grease composition. The grease composition exhibits considerably high resistance to load and accordingly, can be applied to construction equipment which require high resistance to load, such as a hydrauric excavator and a wheel loader.

Abstract:
A porous metal or alloy layer is formed by sintering or the like on a metal backing formed of steel, for example. Copper or a copper-base alloy is generally used for forming the porous metal or alloy layer. The porous metal or alloy layer having the metal backing is impregnated with a mixture comprising 1-25% by volume of lead fluoride, 1-30% by volume of one or both of lead and a lead-tin alloy consisting of 3-30% by weight of tin and the remainder being lead, and the remainder essentially polytetrafluoroethylene, wherein the lead fluoride and one or both of the lead-tin alloy and lead being 2-25% by volume in total, thereby a bearing material of this invention is provided. Depending on the use to which the bearing material is put, at least one additive selected from the group consisting of molybdenum, tungsten disulfide, cadmium oxide, aluminum oxide, calcium fluoride, lithium fluoride, graphite, lead iodide, glass fibers, carbon fibers and a phosphate may be contained in 0.1-5% by volume in the mixture, to improve the performance of the bearing. The bearing material of this kind is suitable for use in shock absorbers of vehicles or the like which move in reciprocatory sliding movement under varying loads.
Abstract:
A lubricant for forming a ferrous metal blank into a preselected configuration by warm- or hot-forming procedures. The lubricant is an alkali-modified borate glass containing a minor mole percent of an alkali metal oxide, preferably sodium oxide. The glass is formed in situ on the surface to be lubricated by depositing on the surface a glass-forming mixture of a source of boron oxide and an alkali metal borate and then heating the mixture to form the glass.
Abstract:
In a lubrication system for an apparatus having a bearing assembly in a lubricant cavity therefor, there is provided means in the lubricant cavity for storing a liquid libricant and for releasing it to effect a supply thereof to the bearing assembly. The storing and releasing means is generally constituted by a mixture of the liquid lubricant, a particulate mass of synthetic fibers, and a particulate mass of discrete, non-fibrous, multi-digited, resilient-type foam particles and wherein the foam particles of the particulate mass thereof are generally saturated with the liquid lubricant.
Abstract:
Bearing materials having low coefficient of friction and high wear resistance comprise 50 to 90 percent by weight of a powdered solid lubricant bonded by a polymerized mixture of unsaturated organic compounds, containing at least 30% divinylbenzene. The solid lubricant is preferably MoS.sub.2 or a mixture of MoS.sub.2 and graphite. The binder is preferably polymerized technical divinylbenzene, a mixture of isomers.
