Evaluation of the wear life of MoS2-bonded-films in tribo-testers with different contact configuration

Abstract

The tribological behavior of MoS2-bonded-films was evaluated by the international standard testing methods, such as ASTM D 2625 and ASTM D 2714. Test results showed that friction and wear performance differed significantly with the contact configuration of tribe-tester, In order to investigate the effect of the test contact configurations on wear life, surface temperatures were measured and evaluated analytically in terms of a frictional heating analysis according to the contact geometry of two test standard methods. Ring-on-block tests in modified test conditions of ASTM D 2625 were also performed. The test results showed that the wear life of MoS2-bonded-films was affected significantly not only by the frictional heating and contact pressure, but also by the contact conformity of the test specimens.
