The solid lubricant having from about twenty-five percent to about seventy percent by volume of a polymeric carrier, about five to seventy-five percent by volume of organic and inorganic extreme pressure additives, about zero to twenty percent by volume synthetic extreme pressure anti-wear liquid oil, and about zero to one percent by volume optical brightener.
Abstract:
An aqueous one step type lubricating agent for efficient cold forging, characterized in that it comprises (A) a water-soluble inorganic salt, (B) a wax and (C) a metal salt of a fatty acid in a form dissolved or dispersed in water, wherein weight ratios of solid contents are 0.60 to 0.70 for (B)/(A) and 0.1 to 0.3 for (C)/(A). The water-soluble inorganic salt can be selected from among a sulfate, a silicate, a borate, a molybdate and a tungstate. As the wax, use can be made of a synthetic wax being dispersible in water and having a melting point of 70 to 150 DEG C. As the metal salt of a fatty acid, use can be made of a reaction product of a saturated fatty acid having 12 to 26 carbon atoms with at least one metal selected among zinc, calcium, barium, aluminum and magnesium.
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 two- or a one-step process and composition which coats metal workpiece surfaces (aluminum, copper, steel, stainless steel, etc.) with a thin lubricant film capable of allowing the metal to be deformed at room temperature. The lubricant consists essentially of polymers, dispersants, high molecular weight waxes and insoluble metallic stearates. With some ferrous surfaces, a separate coating layer is simultaneously formed (in the one-step process) or pre-formed (in the two-step process) at the metal interface, acting as a base for the lubricant. The process, after pickling in a mineral acid to remove scale and oxides, comprises the step(s) of immersing the workpiece either once or twice. The workpiece is then dried in a heated, forced air dryer.
Abstract:
A lubricant composition for the plastic working of metals that does not require a phosphate undercoating, is waterborne, requires only a simple application process of immersion or spraying followed by drying, and provides an excellent lubricating performance comprises synthetic resin, water-soluble inorganic salt, and water. The weight ratio of the content of salt to that of synthetic resin is from 0.25:1 to 9:1. This composition can also contain liquid and/or solid lubricating agent(s) and extreme pressure additive.
