【摘要】 采用自制的销盘式摩擦磨损试验机、扫描电镜和能谱仪,研究了 SiC_P 增强 Al 基复合材料/铬青铜配副在载流条件下的摩擦磨损特性．结果表明:电流对载流条件下的 SiC_P 增强 Al 基复合材料/铬青铜摩擦配副的摩擦学特性有显著影响,随着电流的增加,摩擦系数增加,复合材料的磨损率增大,磨粒磨损、粘着磨损和电弧侵蚀是载流磨损中主要的磨损机制．更多还原

【Abstract】 By using self-made pin-disk tester,scanning electron microscope(SEM)and energy dispelrsive X-ray spectrum(EDS),the electriotribological behaveior of SiC particle-reinforced aluminum composites were investigated against QCr0.5 bronze under electrical sliding.The experimental results indicate the tribo- logical behavior of the compesites/bronze pair was greatly dependet on the electric current,An increase in e- lectrical current resulted in an increase in friction coefficient and wear volume loss of composites pin,Abrasive wear,adhesive wear and arc erosion were the dominant mechanisms during the electrical sliding processes.更多还原
