Abstract:
Nuclear reactor irradiation and laboratory testing were performed on four solid-film lubricants suitable for use in aerospace systems Vitrolube, MLF-5, Almasol SFD-810, and Surf-Kote M-1284. With the exception of Surf-Kote M-1284, all the lubricants were applied by the developing agencies. Several test temperatures were investigated for each lubricant, and in some instances a lubricant was evaluated on two different substrates. Data obtained in this experiment and the statistical treatment employed Weibull plots and ranking of data lead to the conclusion that static exposure to reactor radiation might possibly have had a significant effect on the wear life of the Vitrolube and MLF-5 coatings at 600 F on substrates of M-10 steel and Rene 41, respectively. No significant effects were detected at the other test temperatures or with the other substrate materials employed with these two lubricants. Test results on Almasol SFD-810 were inconclusive as far as determining its radiation resistance however, the lubricant displayed excellent wear life at 1200 and 1500 F. Wear life of Surf-Kote M-1284 was unaffected by the radiation exposure. Wear life of all the lubricants decreased as test temperature was increased.
