摘　　要：采用自制磨料磨损实验机,通过室温和高温滑动磨损实验,研究了钨系热作模具钢3Cr2W8V的干摩擦磨损性能。分析了3Cr2W8V钢室温和高温滑动磨损特性以及磨损面形貌,并对磨损机理进行了探讨。结果表明,初始加热温度对3Cr2W8V钢的抗磨性能有较大影响。在初始加热温度低于500℃时,3Cr2W8V钢具有良好的抗磨性能;当超过500℃以后,钢的抗磨性能迅速下降。低温和高温磨损时,3Cr2W8V钢的磨损面形貌均表现为以微犁削磨损为主,只是在室温时微犁沟浅,在650℃时微犁沟的宽度和深度加大。The dry friction and wear properties of tungsten-based hot-work die steel 3Cr2W8V were studied by using self-made abrasive wear tester through room temperature and high temperature sliding wear tests. The sliding abrasion characteristics and abrasive surface morphology of 3Cr2W8V steel at room temperature and high temperature were studied. The wear mechanism was discussed. The results show that the initial heating temperature has great effects on the anti-wear performance of 3Cr2W8V steel. When the initial heating temperature is below 500 ℃, 3Cr2W8V steel has good anti-wear performance. After over 500 ℃, the abrasion resistance of the steel decreases rapidly. Wearing at room temperature and high temperature, the wear surface of 3Cr2W8V steel is in micro-plow wear. At room temperature, the micro-plowing is slight. At 650 ℃, the width and depth of the micro-plowing increase.
