The grease composition contains substantially no zinc dialkyldithiophosphate. The grease composition achieves high friction characteristics and wear characteristics. A method for transmitting torque of a clutch or a torque limiter mechanism is also disclosed. Moreover, a method for producing a clutch or a torque limiter mechanism is disclosed. The methods utilize the aforementioned grease composition.

The present disclosure provides a soap thickener and methods of making the same. The soap thickener includes a metal soap of a carboxylic acid composition in a base oil, wherein the carboxylic acid composition includes a modified fatty acid composition prepared by performing a pericyclic reaction between an unsaturated small molecule and a fatty acid mixture. The present disclosure further provides lubricating compositions that include the soap thickener of the present disclosure and methods of preparing the same.

A lubricant composition with improved stability and tolerance for water hardness comprises a synthetic wax emulsion; an amine derivative; an emulsifier; and a sequestrant. The synthetic wax emulsion may include poly(ethyleneoxide)-based or poly(propyleneoxide)-based wax emulsions. The amine derivative may include alkyl C.sub.12-C.sub.14 oxy propyl diamine. The lubricant composition can be used for lubricating the passage of a container along a conveyor. The method includes applying the lubricant composition to at least a part of the container or the conveyor in an application cycle, where the application cycle includes a first period of time of dispensing the lubricant composition and a second period of time of not dispensing the lubricant composition.

A solid-state lubricant composition is disclosed. The solid-lubricant contains graphene, an oxide of a metal, and one or more polymeric binders. A method of making a solid-state lubricant coating on various substrates is disclosed. The method includes the steps of making a homogeneous slurry comprising powder of an oxide of a metal, graphene, and a polymeric binder with organic volatile solvent; coating a substrate with the homogeneous slurry with desired thicknesses; and drying the slurry on the substrate naturally or applying additional heat, resulting in a solid lubricant coating on the substrate. Substrates with coated solid composite lubricant show wear reduction and lower coefficient of friction compared with uncoated substrates.

The present invention relates to an aqueous lubricant composition for the lubrication of a stationary or mobile drive system, comprising at least: deionized water; at least one polyalkylene glycol; at least one antifreeze compound chosen from glycols, and at least one phosphorus compound. It also relates to the use of this aqueous lubricant composition for the lubrication and cooling of a stationary or mobile drive system.
