In order to determine the effects of nuclear radiation on Electrofilm #4396 solid film lubricant, test specimens, as received from the vendor, were exposed to four flux levels at ambient temperature in Materials Component Irradiation #6. Results of the tests showed a marked increase in wearlife of irradiated specimens. Significantly, this increase followed a positive slope from Flux I (lowest level) to Flux III, and then a negative slope to Flux IV (highest level). Concurring with nuclear studies over the past few years, the test data indicated that irradiation was responsible for polymerization of the resin binder in the lubricant film, promoting crosslinking of the polymer bond and thereby causing better film adhesion. At Flux III, this phenomenon theoretically reached the maximum permissible radiation level for this polymer. At Flux IV, excessive crosslinking probably caused embrittlement of the polymer, resulting in somewhat decreased adhesion and wear-life characteristics of the lubricant. (auth)
