本文对聚氨酯（ＰＵ）、聚氯乙烯（ＰＶＣ）和一种橡塑复合材料的摩擦系数、相对磨损率进行了测试。在与钢配副的滑动摩擦情形下，用平面定力法测试摩擦系数时，采用位移定量法可以获得稳定的测试结果：用环块摩擦副测试弹性体耐磨性时，对磨环的表面特性是影响测试结果的关键因素，使用砂轮对磨环所得测试结果稳定。
In this paper, the friction coefficient and relative wear rate of polyurethane (PU), polyvinyl chloride (PVC) and a rubber-plastic composites were tested. In the case of sliding friction with steel, when the friction coefficient is measured by the plane force method, a stable test result can be obtained by the displacement quantitative method: When the abrasion resistance of the elastomer is tested by the ring block friction pair, Characteristics are the key factors affecting the test results, the use of grinding wheel ring test results obtained are stable.
