摘要： Compositions and methods are provided that generated a persistent low-friction coating on a solid surface, by application of a mixture of a polyethylene glycol-containing surfactant and a vegetable to the surface. The coating thus generated does not require replenishing during use and persists through rinsing and multiple uses. Surprisingly, markedly reduced friction is found when the surfactant is provided at 3% w/v to 7% w/v in the composition. Such compositions and methods are suitable for application to both mixing and separation operations. Formulation of such compositions with food grade components permits use in food processing.

摘要： A process for preparing a coating on at least part of a tribological surface of a first machine component which, during machine operation, is adapted to be in sliding contact with a tribological surface of a second machine component is provided. The process provides the steps of: (a) applying a polymer formulation onto at least part of the tribological surface of the first machine component to form a coating. The polymer formulation provides an isocyanate that contains two or more isocyanate groups per molecule and an idocyanate-reactive polyol to form polyurethanes; and (b) subjecting at least part of the coating as obtained in step (a) to a curing treatment during which polyurethanes are formed in the coating on the at least part of the tribological surface of the first machine component.

摘要： 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.
