Reported are the effects of irradiation on solid lubricant bearing materials composed of various combinations of solid lubricant materials, plastic binders, and metallic filler materials. Specimens of these solid lubricant bearing materials, along with specimens of solid lubricant coated stainless steel were incorporated in both partial pressure and hydrogen atmospheres in 14 capsules and were irradiated in the shuttle tube facility of the General Electric Test Reactor (GETR). These capsules were exposed to fast neutron fluxes of 10/ sup 13/ nv with resultant specimen temperatures ranging from 130 to 190 deg F. It was generally found that specimens containing Teflon as a plastic binder experienced extreme dimensional instability during irradiation, with several indications of Teflon decomposition. The specimens with DuPont Poly-imide binders and the specimens of stainless steel coated with a solid lubricant material, demonstrated excellert resistance to the irradiation conditions of these experiments.
