Abstract

THE RECENT MAJOR ADVANCES IN SURFACE HARDENING OF POLYMERS BY ION IRRADIATION OPENED UP THE OPPORTUNITY FOR REPLACING MANY CURRENT PARTS IN THE AUTOMOTIVE INDUSTRY. THERE ARE MANY GEAR APPLICATIONS WHERE THE USE OF POLYMERS IS DESIRABLE FROM THE STANDPOINT OF NOISE, COST, AND/OR WEIGHT REDUCTION. HOWEVER, POLYMERS TEND NOT TO DO WELL IN WEAR AND FRICTION APPLICATIONS BECAUSE OF THEIR LOW HARDNESS COMPARED TO STEELS OR OTHER METALS SUITABLE FOR GEAR APPLICATIONS. HIGH ENERGY (MEV) ION IMPLANTATION HAS BEEN SHOWN TO IMPROVE THE HARDNESS OF MANY POLYMERS QUITE SIGNIFICANTLY. SURFACES OF SOME POLYMERS BECAME HARDER THAN THAT OF STEEL AFTER ION IRRADIATION. IN PHASE I, IONS AT ENERGIES IN THE RANGE 2-6 MEV WILL BE IMPLANTED INTO SIX DIFFERENT GLASS REINFORCED POLYMRES CONSIDERED FOR SMALL GEAR APPLICATIONS IN AUTOMOTIVE INDUSTRY. THE IMPLANTED MATERIALS WILL BE CHARACTERIZED FOR SURFACE HARDNESS, STATIC AND DYNAMIC FRICTION COEFFICIENTS, AND WEAR COEFFICIENTS. THE RESULTS WILL BE ANALYZED WITH RESPECT TO THE NEEDS FOR AUTOMOTIVE GEAR APPLICATIONS.
