摘　　要：为分析载荷和温度对B5铜合金材料摩擦磨损性能的影响,采用HSR-2M型往复摩擦磨损试验机对B5铜合金材料进行摩擦磨损试验;利用电子天平、SEM/EDS对试样的磨损量、表面磨损形貌及磨痕处的成分进行了分析检测。结果表明:室温下,B5铜合金的摩擦系数和磨损量随载荷的增加呈现出先增大后减小的趋势。在低载荷下,其磨损机制为塑性变形伴有磨粒磨损,当载荷不断增加时,其磨损机制转变为熔化磨损与氧化磨损共存。在30 N载荷下,随温度的升高,试样的摩擦系数呈下降趋势,磨损量不断增加。在100℃时,其磨损形式主要为犁削磨损、氧化磨损、粘着磨损。当温度不断升高,在200℃时,其磨损形式转变为氧化磨损、剥层磨损。In order to analyze the influence of load and temperature on the friction and wear mechanism of the B5 copper alloy materials,the HSR-2M reciprocating friction and wear tester was used to carry out friction and wear tests on B5 copper alloy materials.The amount of wear,surface wear morphology and composition of the wear marks of the samples were analyzed.by electronic balance,SEM/EDS.The results show that,at room temperature,the friction coefficient and wear amount of B5 copper increases at first and then decreases with the increase of load.Under low load,the wear mechanism is plastic deformation accompanied by abrasive wear.When the load increases,the wear mechanism changes to the coexistence of melting wear and oxidative wear.Under the load of 30 N,with the increase of temperature,the friction coefficient of the sample decreases,and the wear increases.At 100℃,the wear forms are mainly plough wear,oxidation wear and adhesion wear.When the temperature increases continously,at 200℃,the wear forms turn into oxidation wear and delamination wear.
