摘要 利用SEM、EDS等技术观察了变质前后的Mg2Si/Al梯度复合材料和HT200的磨损表面,对比研究了3种材料在不同载荷、不同磨损速率情况下与45钢对磨的干滑动磨损行为。结果表明:变质后的初生Mg2Si颗粒细小、圆整、分布更加均匀,能够起到更强的支撑作用,且不易破碎,很大程度上抑制了塑性变形的出现,抗黏着磨损能力有了明显的提高,说明变质后的复合材料具有更高的耐磨性。实验发现,由于HT200和45钢组成共轭摩擦副,磨损严重,加上复合材料增强颗粒的作用,使得复合材料的耐磨性远远高于HT200。Mg2Si/Al梯度复合材料的失效机制主要是黏着磨损和磨粒磨损。 Dry sliding wear behaviors of HT200,unmodified and modified Mg2Si/Al gradient composites against 45 steel under conditions of different loads and sliding speeds have been investigated.The worn surfaces have been analyzed using SEM and EDS techniques.The results show that the modified composite is superior in wear resistance to the unmodified one,because the fined,round and uniformly distributed primary reinforced phase particles of Mg2Si can exert strong load bearing effect,suppress plastic deformation and consequently enhance the adhesive wear resistance.The conjugate friction pair of HT200 and 45 steel exhibits severer wear,whereas the Mg2Si/Al gradient composites have much batter wear resistance than HT200 because of existence of reinforced particles.The wear mechanisms of Mg2Si/Al gradient composites are mainly adhesive wear and abrasive wear.
