    Abstract: A composite material is described which will provide low friction surfaces for materials in rolling or sliding contact and is self-lubricating and oxidation resistant up to and in excess of about 930.degree. C. The composite is comprised of a metal component which lends strength and elasticity to the structure, a fluoride salt component which provides lubrication and, lastly, a glass component which not only provides oxidation protection to the metal but may also enhance the lubrication qualities of the composite.

    Abstract: SOLID LUBRICANT COMPOSITIONS EMPLOYING POLYBENZIMIDAZOLE RESINS (PBI) AND LUBRICATING PIGMENTS ARE PRODUCED BY ADMIXING FINELY DIVIDED LUBRICANT PIGMENTS INTO A SOLUTION OF POLYBENZIMIDAZOLE RESIN AND SOLVENT THEREFOR. FOR EXAMPLE, A SOLID LUBRICANT COMPOSITION IS PRODUCED BY DISSOLVING POWDERED POLYBENZIMIDAZOLE IN N-METHYLPYRROLIDINE TO FORM A SOLUTION OF ABOUT 25 WEIGHT PERCENT SOLIDS TO WHICH IS ADDED ABOUT 75 WEIGHT PERCENT OF THE SOLID LUBRICANT PIGMENT COMPRISING A MIXTURE OF MOLYBDENUM DISULFIDE (MOS2) AND ANTIMONY TRIOXIDE (SB2O3). THE RESULTING SLURRY IS SPRAYED ONTO THE SURFACE OF A TEST SPECIMEN AND THE WETTED TEST SPECIMEN IS PLACED INTO AN OVEN WHERE IT IS DRIED AT 200*F. FOR ONE HOUR. IT IS THEN HEATED AT 575*F. FOR ONE HOUR TO EFFECT CROSS-LINKING AND BONDING TO SPECIMEN SURFACE. OTHER SOLID LURBICANT PIGMENTS WHICH MAY BE USED INCLUDE MOLYBDENUM DISELENIDE, GRAPHITE, TUNGSTEN DISULFIDE, TUNGSTEN DISELENIDE AND THE LIKE. ALTERNATIVELY, THE PBI COMPOSITION CAN BE LAMINATED WITH FIBERS OF GLASS, GRAPHITE AND THE LIKE TO MAKE PREFORMED STRUCTURES WHICH CAN BE MACHINED TO FIT AGAINST THE METAL SURFACE TO BE LUBRICATED. FIBER GLASS OR GRAPHITE FIBER REINFORCED BEARING COMPONENTS ARE FORMED UTILIZING THE PBI COMPOSITION AS A BINDER FOR THE FIBERS AS WELL AS FOR THE LUBRICATING PIGMENT.
