采用销盘式摩擦磨损试验机和双盘摩擦磨损试验机研究了1.41wt%C超高碳钢（UHCS-1.41C）与GCr 15轴承钢在不同载荷下的摩擦学行为。用光学显微镜、能谱仪和扫描电镜对试样的磨损表面进行了分析。通过XRD测定残余奥氏体。结果表明：UHCS-1.41C钢的摩擦系数在低载荷（6 N）下高于GCr 15钢，在高载荷（10 N、20 N）下低于GCr 15钢。双盘磨损试验结果表明，UHCS-1.41C钢的磨损率始终低于GCr 15钢。UHCS-1.41C具有更强的加工硬化能力，在双盘试验中比GCr 15具有更高的耐磨性。
The tribological behavior of 1.41 wt% C ultrahigh-carbon steel (UHCS-1.41C) was investigated in comparison with a GCr15 bearing steel with a pin-on-disk and a two-disk tribometer at varying applied loads in ambient conditions. The wear surfaces of the specimens were examined with an optical microscope, EDX, and SEM. The retained austenite was measured by XRD. The results show that the friction coefficient of UHCS-1.41C is higher than that of GCr15 at a low load (6 N); however, it becomes lower than that of GCr15 at higher loads (10 N, 20 N). The wear rate of UHCS-1.41C is always lower than that of GCr15 according to the results of the two-disk test. UHCS-1.41C exhibits a stronger work hardening ability, which results in a higher resistance to wear than that of GCr15 during the two-disk test.
