05 . 02 wear rate of materials in unlubricated rubbing contact using a thrust washer testing machine , test for 用止推垫圈试验机测定在非润滑摩擦接触中材料的磨损率的试验
But the wear performance showed that the wear capacity reduced considerably and it had a lower friction coefficient 但是耐磨实验说明,复合镀层的磨损率明显降低,而且镀层的摩擦系数很小。
The results of friction and wear test showed that this wearable composite has lower wear rating , but has bigger friction coefficient 通过对材料进行摩擦磨损试验,结果表面该耐磨复合材料的磨损率较小,但摩擦系数偏大。
At the same time , the study shows that adding 30wt cf has little influence on friction coefficient of bismaleimide matrix wearable composite , but it can reduce the wear rating greatly 研究同时表明, 30份碳纤维的加入,对改性双马树脂基耐磨复合材料的摩擦系数影响不大,却大大降低了材料的磨损率。
At present , the method to process information of lubricating oil in our country is based on the ratio of wear and tear . this method is simple and impersonal , but its function of quantitative analysis is not satisfying 目前我国发动机滑油信息的处理方法只是将所测的数据(主要是浓度)转化为磨损率,然后根据磨损率增加的缓慢程度,来决定是否对发动机进行维修。
