摘　　要：采用自制的销盘式干滑动摩擦磨损试验机,研究了45钢配副的摩擦磨损特性。结果表明:材料的磨损率随着速度、载荷的增加而增大;摩擦系数随着速度、载荷的增加而减小。磨损机理主要为磨粒磨损和粘着磨损。By using self-made dry sliding friction pin-disk tester, the dry sliding friction and wear characteristics of 45 were investigated. The experimental results indicate that the wear rate of pin accretion with connecting pressure and sliding speed increase, friction coefficient minish with the connecting pressure and sliding speed increase. The wear mechanisms of 45 are mainly abrasive wear and adhesive wear.
