摘　　要：对TC4合金和P110油管钢在不同温度下的摩擦磨损性能进行对比研究,分析其摩擦系数、磨损率和磨痕形貌随温度的变化规律,探讨磨损机制。结果表明:P110油管钢的耐磨性明显优于TC4合金,TC4合金的耐磨性随温度的升高无显著变化,磨痕呈犁沟形貌,在较低温度时的磨损机制为剥层磨损、黏着磨损和疲劳磨损,在较高温度时为剥层磨损、黏着磨损和氧化磨损;P110油管钢耐磨性随温度的升高而降低,在较低温度时磨痕呈磨坑形貌,磨损机制为剥层磨损和磨粒磨损,在较高温度时磨痕形貌呈犁沟形貌,主要为剥层磨损、黏着磨损和氧化磨损。The friction wear properties of TC4 alloy and P110 tubing steel were comparatively studied at different temperatures. The changing rules of the wear rate, frication coefficient and topography of wear mark with the temperature were analyzed and the wear mechanism was also discussed. The results show that the wear resistance of P110 tubing steel excels obviously that of TC4 alloy. The wear resistance of TC4 changes a little with temperature rising and the wear mark is furrow morphology. The wear mechanism of TC4 alloy is delamination abrasion, adhesive abrasion and fatigue abrasion at lower temperature and delamination abrasion, adhesive abrasion and oxidation abrasion at higher temperature. The wear resistance of P110 tubing steel is decreased with temperature rising. The wear mark of P110 tubing steel is wear pit morphology and the wear mechanism is delamination abrasion and abrasive grain abrasion at lower temperature, while the wear mark is furrow morphology and the wear mechanism is delamination abrasion, adhesive abrasion and oxidation abrasion at higher temperature
