摘要
本文研究了用电沉积法制备的碳毡／铜复合材料的摩擦磨损特性。研究结果表明，在干摩擦条件下，复合材料的耐磨性主要与摩擦副间维持连续有效碳膜时间的长短有关，该时间取决于碳毡纤维的体积分数。在油润滑条件下，碳毡／铜复合材料的耐磨性与复合材料的硬度及纤维弯曲和破断所消耗能量的多少有关。在这两种条件下，复合材料的耐磨性均明显优于常用耐磨铜合金ＺＱＳｎ６－６－３。
The friction and wear properties of carbon fiber felt copper composites fabricated by electrodeposition were studied. Results showed that under the condition of dry friction, the wear resistance of the composites was chiefly related to the existing time of a continuous and effective carbon film formed on both surfaces of the mating pair, which was determined by the carbon fiber volume of the composites. The wear resistance of the composites depended on the hardness of the composites and the extra energy necessary to bend and break the fibers under lubricated condition. In both cases, the wear resistance of the composites was much better than that of ZQSn6 6 3.
