This study was performed through a pad-on-disk type friction tester under different temperature conditions. Results showed that temperature has a significant effect on the dynamic tribology performance. At 100 degrees C, friction coefficient and wear rate after the running-in stage varied little with time. At 250 degrees C, friction coefficient after the running-in stage increased gradually and then tended to be stable, while wear rate decreased gradually. From 100 to 350 degrees C, friction coefficient increased first as a function of temperature, but decreased sharply when the temperature was over 250 degrees C. Simultaneously, wear rate also increased sharply over 250 degrees C. Additionally, three dynamic evolution models of worn surfaces corresponding to different cases were established.
