EFFECTS OF REACTOR RADIATION ON A CERAMICBONDED, A RESIN-BONDED, AND A METAL-MATRIXBONDED SOLID-FILM LUBRICANT

Abstract

Three solid-film lubricant formulations - PbS + MoS2 + B2O3, GD/FW dynalube, and Almasol SFD-560 - were exposed to reactor radiation and tested for wear-life on a Hohman A-6 wear tester. Rub shoes were of Rex AAA steel, load per shoe was 110 lb, and sliding speed was 128 ft/min. Substrate materials were T-1 tool steel for GD/FW Dynalube and Timken standard test races (T-54148-3-233) for the other two lubricants. Several test temperatures up to 1150F were employed. The solid-film lubricant specimens received an average radiation exposure of 1.7 x 10 to the 11th power ergs/ gm(C) of gammas and 3.7 x 10 to the 16th power n/sq cm (E>2.9 Mev) of neutrons. Significant decreases in wear life occurred at 80 and 900F for Dynalube and at 900F for SFD-560; PbS + MoS2 + B2O3 showed no change; and SFD-560 improved markedly at 80F.
