Abstract:
At least one kind of coating modifier selected from polyamidimide resin, epoxysilane and epoxy resin, and at least one kind of hard particles selected from silicon nitride and alumina are impregnated into a dry coating lubricant. The coating layer of a dry coating lubricant is formed on the sliding surface of the base material of a sliding member, with the surface roughness of this coating layer set to up to 3 μmRz in a ten point height of irregularities. The coating layer of a dry coating lubricant is formed on the sliding surface of the base material of a sliding member, the coating layer being formed in a film thickness of at least 10 μm on at least part of the sliding surface of the base material.
Abstract:
According to the invention there is provided a liquid friction control composition characterized as either having a high and positive friction characteristic or a low and neutral friction characteristic, comprising a retentivity agent. The liquid friction control composition may also comprise other components such as a solid lubricant, a wetting agent, a consistency modifier, and a preservative. The liquid friction control compositions may be used to modify the interfacial friction characteristics in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems.

Abstract:
A water-based release agent comprises: 30-99 % total solids by weight chemically exfoliated vermiculite, and 1-70 % total solids by weight of a plate-like filler. Such release agents are particularly suitable for use with gaskets. An anisotropic release agent is formed from which it is easy to release other materials.
Abstract:
The present invention relates to novel lubricant and friction modifier compositions optionally comprising a solid lubricant and a binding agent in water medium suitable for lubricating steel-steel interfaces such as tractor-trailer couplings, rail-wheel systems and other heavy duty applications. The invention also relates to compositions described above which include friction modifiers with high or very high and positive coefficients of friction such that the coefficient of friction is considerably higher than the solid lubricant. The invention further relates to compositions comprising a binding agent and a friction modifier with a very high and positive coefficient of friction in a water medium.
Abstract:
Waterborne lubricants comprising: (A) water-soluble inorganic salt; (B) homogeneously dispersed solid lubricant; (C) at least one homogeneously emulsified substance selected from mineral oils, animal and plant oils and fats, and synthetic oils; (D) surfactant; and (E) water, in which the weight ratio (B)/(A) is from 0.05:1 to 2:1 and the weight ratio {C/(A + B)} is from 0.05:1 to 1:1, provide a one-step, highly lubricating waterborne lubricant for use in the cold plastic working of metals. This waterborne lubricant can replace the conversion coating treatment (phosphate, oxalate, etc.) + reactive soap treatment combined lubrication system now in general use and is free of the environmental issues associated with the combined lubrication system, provides for facile coating removal, and is not subject to the decline in seizure resistance caused by nonuniform add-on when large numbers of workpieces are treated together by immersion.
Abstract:
A stearate free solid lubricant for cold working of metals contains approximately equal amounts of an alkene-acrylate ionomer and an alkoxylated alcohol in which the alcohol moiety has from 18-60 carbon atoms and the alkoxylate block has about the same number of carbon atoms. This lubricant can be conveniently applied from aqueous solution/suspension and works effectively even when the underlying steel surface has no conversion coating, which is usually required with stearate lubricants for best results.
