Studies on Dynamic Tribology Properties of Friction Materials by Using an Approximate In Situ Observation for Worn SurfacesSource: Journal of Tribology:;2018:;volume( 140 ):;issue: 005::page 51607DOI: 10.1115/1.4040053Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper primarily focused on the dynamic tribology properties of one certain nonasbestos organic (NAO) friction material by using an approximate in situ method. 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 °C, friction coefficient and wear rate after the running-in stage varied little with time. At 250 °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 °C, friction coefficient increased first as a function of temperature, but decreased sharply when the temperature was over 250 °C. Simultaneously, wear rate also increased sharply over 250 °C. Additionally, three dynamic evolution models of worn surfaces corresponding to different cases were established.
