“…Generally, polyimide (PI) shows outstanding representation on friction and anti-wear 3 , and in order to find out the internal nature of PI, researchers always put an emphasis on the tribological mechanisms of PI and PI composites under different conditions [4][5][6] . Although tribological properties of PI composites filled with kinds of fibers [7][8][9] , and nanoparticles 10, 11 had been investigated thoroughly matched with various steel pairs, meanwhile the important role of transfer film had been discussed in detail.…”

Tribological properties of thermosetting polyimide (TPI) mated with Si 3 N 4 , Al 2 O 3 and GCR15 balls are investigated from room temperature to 300℃. TPI mated with ceramic balls, shows lower coefficient of friction (COF) and wear rate (WR) under room temperature, due to the inexistence of transfer film on TPI-ceramic balls, which is demonstrated by Energy Dispersive Spectrometer (EDS) and different wear mechanisms. And a conclusion is drawn that transfer film can hardly form on ceramic balls due to the low chemical activities of ceramic materials, Downloaded by [UQ Library] at 02:48 13 July 2015 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 especially under higher load conditions. Under high temperatures, COFs of TPI-ceramic balls present diverse trend compared to TPI-GCR15. Moreover, transfer films on ceramic balls begin to form as the temperature rising, which is easily determined by EDS of tribological marks on ceramic balls. The differences presented above mainly can be ascribed to the diversities of different properties of mated balls.

“…Three different indenters from Edmund Optics were used in this work: a borosilicate glass sphere (reference BK7) of radius 500 µm, and sapphire spheres of radii 2 mm and 4.66 mm. The average roughness of the indenters was low enough to neglect local plasticity under micro-roughness peaks [30]. They were washed in ethanol and dried under nitrogen flow before measurements.…”
