摘　　要：以几种常用金属材料(45#、25CrMn、40CrNiM)o组成摩擦副作为研究对象,在油润滑条件下采用M-200型磨损试验机进行试验,研究了不同滑动速度和正压力条件下摩擦副之间的摩擦磨损规律。试验结果表明:25CrMn与45#组成摩擦副时结合效果最好,具有较好的摩擦磨损性能;在滑动速度较低时,对摩擦副施加的载荷是影响摩擦副间摩擦因数的主要因素;摩擦副间主要磨损形式是粘着磨损,但随摩擦副间接触压力和滑动速度的增加其磨损机制逐渐由粘着磨损向磨粒磨损和剥落磨损转化过渡。The friction and wear properties of several common metal materials （5^#,25CrMn,40CrNiMo） friction pair under oil lubrication were tested on M-200 Type wear tester, and the effects of sliding speed and pressure on friction wear rules were investigated. The results showed that the 25CrMn/45^# steel pair had better tribological and wear performance, the load was the main factor which influences the friction of the material at the low sliding speed, the main wear form was adhesive wear, but the wear mechanism gradually became from adhesive wear to abrasive wear and flaking wear with the contact pressure and sliding speed increased.
