通过销-盘式摩擦磨损试验机研究了变形铝合金的干摩擦磨损性能,在干摩擦条件下测量了不同系列变形铝合金与不锈钢组成的摩擦副的磨损质量损失和摩擦系数,用扫描电镜(SEM+EDXA)观察其磨损表面及磨屑,并对其磨损机理进行了探讨分析。实验表明,在低速和室温条件下,不同系列变形铝合金平均摩擦系数不同,摩擦系数在整个实验过程中呈湍流状波动;变形铝合金的磨损机制主要以粘着、磨粒磨损为主,同时伴有氧化磨损;其中试样E#具有良好的耐磨性及干摩擦性能。
The dry friction and wear properties of the deformed aluminum alloy were investigated by pin-disc friction and wear tester. The wear mass loss and friction coefficient of the friction couple composed of different series of deformed aluminum alloy and stainless steel were measured under dry friction condition. SEM + EDXA) to observe the wear surface and wear debris, and its wear mechanism were discussed. The experimental results show that the average friction coefficient of different series of deformed aluminum alloy is different at low speed and room temperature, and the friction coefficient fluctuates turbulently throughout the experiment. The wear mechanism of the deformed aluminum alloy mainly consists of adhesion and abrasive wear, Oxidation wear; sample E # has good wear resistance and dry friction properties.
