Abstract
The present lubricant compositions comprise a mixture of graphite, molybdenum disulfide and polytetrafluoroethylene in specified proportions within a matrix of an organic resin. When applied to surfaces that are in sliding contact with one another the compositions exhibit high wear resistance, good initial conformability, and a coefficient of friction following use that is lower than the initial coefficient of friction. The compositions are particularly suited for application to engine pistons.
