Wear-life of the MoS2 film was evaluated by in-situ tribological testing under 5 eV atomic oxygen exposures which simulate LEO atomic oxygen environment. A combination of a laser-detonation atomic oxygen source and a conventional pin-on-disk friction tester was used to perform tribological tests. It was confirmed that the friction coefficient was not affected by atomic oxygen exposure when atomic oxygen fluence was low; however, the friction coefficient increased with increasing atomic oxygen fluence and it reached as high as 0.05 (seven times larger than the normal value) at the atomic oxygen fluence of 3.4×1016 atoms/cm2/cycle. Effect of atomic oxygen on the wear-life of the film has much more drastic. With atomic oxygen fluence of 1.7×1016 atoms/cm2/cycle, wear-life of the film was reduced one ninth of the ex-situ testing result of the same film. It was also observed that the wear-life of the film was inversely proportional to the atomic oxygen fluence between every sliding motion.
