Abstract

Metal, carbon, or other original surfaces of articles, such as pneumatic and hydraulic cylinders, having scored or marred surfaces can be rehabilitated by applying to them a composition consisting essentially of a mixture of powdered molybdenum disulfide and epoxy resin, curing the resin, and removing excess material. The coating is as hard as steel, has lubricative action, and can withstand high temperatures.
