摘　　要：在高温磨损试验机上进行TC11合金与GCr15钢在25和600℃的干滑动磨损实验。研究摩擦副(钛合金与对摩钢)的磨损行为,并探讨磨损机制。结果表明:在25℃时,TC11合金具有极高的磨损率并随着载荷快速增加,而GCr15钢的磨损率则随载荷提高略有增加,且处于较低值。在高温600℃时,TC11合金和GCr15钢均表现为随着载荷增加,磨损率变化较小的趋势,且处于极低的值。研究发现高温下摩擦氧化物的形成导致了TC11合金和GCr15钢极低的磨损率。可以认为,在高温下TC11合金与GCr15钢是一种理想的摩擦副。Dry sliding wear tests of TC11 alloy and GCr15 steel at 25 and 600 ℃ were performed on a high-temperature wear tester.The wear behaviors of the tribo-pair（TC11 alloy and GCr15 steel） were studied and the wear mechanisms were also explored.The results show that at 25 ℃,TC11 alloy presents extremely-high wear rates which increases rapidly with the load increasing.But GCr15 steel gives lower wear rates which have slight variation with an increase of load.When the temperature increases to 600 ℃,the wear rates of TC11 alloy and GCr15 steel reach extremely low values and they are decreased with an increase of load.Tribo-oxide layers are found to be attributed to such low wear rate.It can be suggested that the tribo-pair of the titanium alloy against AISI 52100 steel is an ideal sliding system for elevated-temperature applications.
