    Abstract: This disclosure is directed to copper-lead alloys for lubricants and bearings. The copper-lead alloys have a fine and even dispersion of the lead particles in a copper matrix. The alloy is made by adding an effective amount of a homogeneity promoter to a mixture of molten lead and copper. The promoter comprises elemental carbon and an alkali and/or alkaline earth metal compound capable of reacting to form a gas, or a rare earth metal compound in the form of an oxide or carbonate. The lubricants comprise the copper-lead alloy in powdered form, as a dry lubricant, in a carrier, or in a base of a grease or oil. The bearings comprise the copper-lead alloy as a load-bearing surface.

    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.
