Abstract: A relatively thick, solid film lubricant comprising a polyphenylene sulfide binder having a finely divided, solid phase lubricating material dispersed throughout the binder, wherein the polyphenylene sulfide polymer has a chain of from 6 to 12 recurring C6H4-S units in its initial state prior to curing. The lubricant layer is heat cured on the surface of a bearing substrate to advance the polymerization of the binder to an infusible state in which the binder is resistant to thermal degradation at useful temperatures in air on the order of 1000* F. The thickness of the layer may be from 0.001 to 0.01 inch without flaking under load.
