摘　　要：采用金相显微镜、XRD、SEM和UMT摩擦磨损试验机等手段,对复杂黄铜(HAl61-4-3-1)和硅锰黄铜(HMn60-3-1-0.75)的显微组织和耐磨性能进行了研究。实验结果显示,HAl61-4-3-1及HMn60-3-1-0.75耐磨黄铜主要由α相、β相和强化相三相构成,其中α、β相的主要元素为Cu、Zn。复杂黄铜HAl61-4-3-1颗粒状强化相以Al、Co、Ni、Fe、Si为主。硅锰黄铜HMn60-3-1-0.75强化相为Mn_(5)Si_(3)。与HMn60-3-1-0.75相比,HAl61-4-3-1黄铜具有更高的硬度,较小的摩擦系数和磨损量,具体数值分别为181.3HV、0.177和1.13×10^(-3)g。这种差异主要是由于HAl61-4-3-1黄铜的基体硬度大于HMn60-3-1-0.75,在磨损时犁沟效应减轻,剥落和粘着程度也减小。通过对HAl61-4-3-1磨损形貌的分析认为,其主要的磨损形式为磨粒磨损和粘着磨损,并伴有少量的疲劳磨损与氧化磨损。Using metallographic microscopy,X-ray diffraction(XRD),scanning electron microscopy(SEM),and a UMT tribological tester,the microstructure and wear resistance of complex brass(HAl61-4-3-1)and silicon-manganese brass(HMn60-3-1-0.75)were studied.The experimental results indicate that both HAl61-4-3-1 and HMn60-3-1-0.75 wear-resistant brass are mainly composed of three phases:needle-likeαphase,βphase,and a strengthening phase,with copper(Cu)and zinc(Zn)as the primary components of theαandβphases.The particle-like strengthening phase in HAl61-4-3-1 wear-resistant brass is primarily composed of aluminum(Al),cobalt(Co),nickel(Ni),iron(Fe),and silicon(Si).In contrast,the strengthening phase in HMn60-3-1-0.75 wear-resistant brass is identified as needle-like Mn_(5)Si_(3).Compared to HMn60-3-1-0.75,HAl61-4-3-1 brass exhibits higher hardness,lower friction coefficient,and reduced wear volume,with specific values of 181.3HV,0.177,and 1.13×10^(-3) g,respectively.This difference is mainly due to the matrix hardness of HAl61-4-3-1 brass is greater than that of HMn 60-3-1-0.75.The furrow effect is reduced and the peeling and adhesion is reduced.Through the analysis of HAl61-4-3-1 wear morphology,its main wear forms are grinding and adhesive wear,with a small amount of fatigue and oxidative wear.
