Relation between wear-sliding distance and wear-sliding velocity curves

在无润滑条件下，对滑动速度对金属磨损的影响进行了数值研究。磨损数据通常是通过在试运行结束时直接测量特定滑动距离的速度损失来获得的。如果测试涉及特定滑动距离或特定滑动重复次数，当磨损率在滑动距离上不恒定时，结果会非常不同。本文报告了将滑动距离（或重复次数）作为相关因素考虑磨损与滑动速度关系的研究结果。绘制了总磨损量、滑动速度和滑动距离（重复次数）三项的三维图形。在研究磨损与滑动速度的关系时，滑动距离是一个重要的因素。也就是说，从这些图中，可以通过磨损-滑动距离曲线来解释磨损-滑动速度曲线的峰谷，进而通过重复滑动过程中严重磨损和轻微磨损的过渡来解释特定滑动速度下出现的金属磨损类型。

Nmerical studies have been reported on the influence of sliding velocity on the wear of metals under unlubricated conditions. The wear data are usually obtained by a direct measurement of the velumetric loss at the end of the test run for a specific amount of sliding distance. The results are very differenta if the tests involve a specific sliding distance or a specific number of sliding repetitions, when the wear rate is not constant over the sliding distance.This paper reports the results of an investigation when the wear vs. sliding velocity relationship is considered with the sliding distance (or numger of repetitions) as a correlating factor. Thiree dimensional graphs in the three terms : total wear, sliding velocity, and sliding distance (repetitions) were drawn. The sliding distance can be seen to be an important factor in the study of the wear vs. sliding velocity relation. That is, from these graphs, peaks and valleys in a wear-sliding velocity curve were elucidated through wear-sliding distance curves and, furthermore, the metallic wear type appearing at a specific sliding velocity was explained by way of the transition between the severe wear and mild wear during repetitious sliding.
