在较宽的负荷、速度和温度范围内在栓-盘试验机上对铜表面进行了滑动试验,测定了摩擦、磨损和表面粗糙度。试验表明存在着高摩擦磨损,低摩擦磨损及其过渡状态。根据在滑动表面上氧化铜层的连续形成和去除导出了一个定量模式,由此可以预料,只有在金属平面上氧化层的形成速率大于磨损去除速率的情况下才能得到低的摩擦磨损,否则将产生某些金属与金属的接触,摩擦磨损会相应增大。该模式的预测与试验数据相当一致。也与以前在升高温度下铜滑动表面的摩擦转移数据相符合。
The copper surface was subjected to a sliding test on a peg-plate tester over a wide range of load, speed and temperature conditions to measure friction, wear and surface roughness. Experiments show that there is high friction and wear, low friction and wear and transition state. A quantitative pattern was derived from the continuous formation and removal of the copper oxide layer on the sliding surface whereby it can be expected that low friction and wear will only be achieved if the rate of formation of the oxide layer on the metal surface is greater than the wear removal rate, Produce some metal and metal contact, friction and wear will be increased accordingly. The prediction of this model is in good agreement with the experimental data. It is also consistent with previous data on the friction transfer of copper sliding surfaces at elevated temperatures.
