Al2O3连续增强铝基复合材料的干摩擦磨损特性
Dry Friction and Wear Characteristics of Al2O3 Continuous-Reinforced Aluminum Based Composites
摘 要
通过摩擦磨损试验对比研究了含质量分数18%SiC颗粒和不含SiC颗粒的Al2O3连续增强铝基复合材料与NAO(无石棉有机材料)配副的干滑动摩擦磨损行为。结果表明: 复合材料在较低的滑动速度(0.628 m·s-1)下, 最大启动摩擦因数随正压力的增大而降低; 在较高的滑动速度(2.512 m·s-1)下, 最大启动摩擦因数随正压力的增大呈先减小后增大的趋势; 正压力一定时, 最大启动摩擦因数随滑动速度的增大先减小后增大; 含SiC的Al2O3连续增强铝基复合材料比不含SiC的Al2O3连续增强铝基复合材料具有更高的摩擦因数和更好的耐磨性。

Abstract
The friction and wear behavior of alumina continuous-reinforced aluminum based composites with and without 18wt.% SiC particles against NAO (organic materials without asbestos) under dry sliding friction was comparatively studied through friction and wear testing. Results show that the maximal starting friction coefficient reduced at low sliding speed (0.628 m·s-1) but decreased first and then increased at high sliding speed (2.512 m·s-1) with the increase of normal pressure. The maximal starting friction coefficient also decreased first and then increased with the increase of sliding speed under constant pressure. The composite with SiC had higher friction coefficient and better wear resistance compared with the composite without SiC.
