Effect of Sliding Speed and Loads on Tribological Behaviors of Iron and Cobalt-based High-Temperature Alloys Against A12O3 Balls

摘要：

　　The dry sliding wear behaviors of iron and cobalt-based high-temperature alloys against Al2O3 with different sliding speed under various loads were investigated using a ball-on-disc tribo-tester.The friction coefficient of both high-temperature alloys decreased with the increasing speed and load.The GH605 exhibited the stronger wear resistance than GH2132 under all test conditions.The adhesion layer and oxides were found on the worn surface of Al2O3, and the high-temperature alloy would react with air and the wear mechanisms might be adhesive wear and oxidative wear.
