中文摘要:
      利用UMT-2 型摩擦磨损试验机研究了T6态Al-10Si-5Cu-0.75Mg 合金的干滑动摩擦磨损性能,采取SEM、XRD、EDS等方法分析了合金在不同转速和载荷下的摩擦磨损行为。结果表明:合金的磨损率随转速和载荷的增加而增大,但在800 r/min的高转速下仍具有良好的耐磨性,15N高载荷时的磨损率相对于5N低载荷时只增加了291%,属于轻微磨损;摩擦系数的平均值在0.35-0.40范围内变化,且随时间的变化不大,具有较高的稳定性;另外,磨损机制由低速轻载时的磨粒磨损、粘着磨损向高速重载时的剥层磨损、氧化磨损转变。

英文摘要:
      The dry sliding friction wear test of T6 treated Al-10Si-5Cu-0.75Mg alloy was performed with UMT-2 tribometer. The wear mechanisms of the alloy under different load and revolving speed were analyzed by means of SEM, XRD and EDS. The results reveal that the wear rate of Al-10Si-5Cu-0.75Mg alloy is increased with the increase of revolving speed and applied load. but under 800 r/min high revolving speed, Al-10Si-5Cu-0.75Mg alloy still has a good wear resistance. The wear rate of the Al-10Si-5Cu-0.75Mg alloy under 15N applied load is only increase by 291% compared with 5N applied load, this belongs to mild wear. The average friction coefficient changes within the range from 0.35 to 0.40, and the change is small over time, which indicates a strong stability. Meanwhile, as the applied load increases, the wear mechanism is changed from the abrasive wear and the adhesive wear of low applied speed to the delamination wear and the oxidative wear of high applied speed. Keywords: Al-10Si-5Cu-0.75Mg alloy; wear rate; friction coefficient; wear mechanism
