| 中文摘要 | In this work, reciprocating ball-on-flat sliding friction and wear tests as well as two-body abrasive wear tests were performed on Zr(2)Al(3)C(4), a new type of ceramic material. In the sliding wear tests, a Si(3)N(4) ball and an AISI 52100 steel ball were used as counter materials. When Zr(2)Al(3)C(4) was slid against an AISI 52100 ball, the coefficient of friction (COF) was as low as 0.20-0.42, being independent of normal loads, and the wear rates of Zr(2)Al(3)C(4) and AISI 52100 steel were in the range of 10(-4)-10(-5) mm(3)/m. A tribofilm between the tribopair was presumed to be responsible for the low COF and wear rate. According to Raman and energy-dispersive spectroscopy analysis, the tribofilm consists of a mixture of oxides of Zr, Al, and Fe as well as amorphous carbon. When Zr(2)Al(3)C(4) was slid against a Si(3)N(4) ball, a transition from mild wear to severe wear was observed as the normal load increased. The transition occurs under certain contact stresses after a damage-accumulating period. In the two-body abrasive wear test, surface chipping and fragmentation resulting from coalescence of surface and subsurface microcracks were the main material removal mechanisms of Zr(2)Al(3)C(4). |
