摘　　要：采用粉末冶金法制备了炭纤维增强铜锡锌基复合材料(Cf/Cu-Sn-Zn)和ZQ Sn663锡青铜,并对其力学性能和摩擦磨损性能进行了对比研究.结果表明:当炭纤维的体积分数fφ≤12%时,Cf/Cu-Sn-Zn复合材料的力学性能高于ZQ Sn663锡青铜;Cf/Cu-Sn-Zn复合材料的比磨损率小于ZQ Sn663锡青铜,当炭纤维体积分数fφ=12%时,复合材料的摩擦磨损性能最佳;在摩擦磨损过程中,Cf/Cu-Sn-Zn复合材料的磨损机制主要为粘着磨损,而锡青铜呈现出粘着磨损和磨粒磨损特征.Short carbon fiber reinforced Cu-Sn-Zn matrix composites and bronze with composition of Cu, 6% Sn, 6%Zn and 3%Pb （663 bronze） were prepared by powder metallurgy method. Their mechanical properties and tribological performance were investigated as a comparison. Experiments indicated that wear rate and friction coefficient fiber was no more than 12 SEM observation indicated of 663 bronze was adhesive of % th composites were lower than that of bronze, and when volume fraction of carbon , mechanical performance of the at dominant wear mechanism of wear and abrasive wear. composites was prior to that of the bronze. the composites was adhesive wear, while that
