The present invention relates to a lubricated system comprising: a) a component comprising a first surface which is a diamond-like carbon (DLC) surface; b) a component comprising a second surface; and c) a lubricant formulation interposed between the first surface and second surface. The lubricant formulation comprises: i) a base stock; ii) a molybdenum compound; iii) an organic polymer comprising a hydrophobic polymeric sub unit selected from polyesters and functionalised polyolefins and a hydrophilic polymeric sub unit selected from polyethers; and iv) optionally, other additives. The combination of the molybdenum compound and the organic polymer in the lubricant formulation reduces the wear on one or more of the surfaces in the lubricated system when compared with using the molybdenum containing friction modifier alone.

An automotive axle includes a housing including gears and a bath lubricating the gears, the bath including gear oil and about 0.1 to 5 wt. % secondary alcohol ethoxylate based on total weight of the bath such that during automotive operation at temperatures less than a threshold, reverse micelles form to trap air bubbles in the bath, emulsifying the bath, and at temperatures greater than the threshold, the reverse micelles dissipate.

A water-soluble metal working oil agent which can be prevented from being scattered in the form of mists for a long period when used for the cutting processing, grinding processing and the like of metallic materials is provided. A method for producing the water-soluble metal working oil agent is described. The water-soluble metal working oil agent includes a polyalkylene oxide having a weight average molecular weight of 100,000 to 1,000,000 and water.

A composition and method for reducing the coefficient of friction and required pulling force of a wire or cable are provided. A composition of aqueous emulsion is provided that is environmentally friendly, halogen free and solvent free. The composition is compatible with various types of insulating materials and may be applied after the wire or cable is cooled and also by spraying or submerging the wire or cable in a bath. The composition contains lubricating agents that provide lower coefficient of friction for wire or cable installation and continuous wire or cable surface lubrication thereafter.
