通过搅拌法加入Al2O3颗粒制备颗粒增强Al-0.97%Mn基复合材料,在不同载荷下磨损性能方面与Al-0.9%Mn合金对比研究。结果表明:在滑动摩擦磨损条件下,随着载荷增加,Al-0.9%Mn合金的磨损失重速度比Al-0.97%Mn基复合材料快得多;随着干、湿摩擦环境变化,Al-0.9%Mn合金的摩擦系数不稳定,磨损程度加剧而Al-0.97%Mn基复合材料的摩擦系数比较稳定,表现良好的耐磨性能。因此Al2O3颗粒的加入使变形铝锰合金在滑动磨损性能上得到明显的提高。
Comparative Study on Al-0.9% Mn Alloy with Particle Reinforced Al-0.97% Mn Matrix Composites by Addition of Al2O3 Particles by Agitation Method. The results show that the wear loss rate of Al-0.9% Mn alloy is much faster than that of Al-0.97% Mn-based composite under the condition of sliding friction and wear. With the increase of load, Al- The friction coefficient of% Mn alloy is unstable and the degree of wear is aggravated, while the friction coefficient of Al-0.97% Mn-based composite material is relatively stable, showing good wear resistance. Therefore, the addition of Al2O3 particles makes the deformation of aluminum-manganese alloy in the sliding wear performance has been significantly improved.
