纳米SiC颗粒强化AA6061的磨粒磨损行为李晓丹,翟玉春,马军平东北大学材料与冶金学院摘 要:实验制备了纳米SiC颗粒强化AA6061基材料,并考察了其微观组织,硬度及磨损性能.结果表明:在20 N载荷下,强化试样的磨损率及摩擦系数均低于AA6061基体,其中0.6%SiC/AA6061复合材料的磨损率较基体降低50%.这主要是由于SiC颗粒自身良好的载荷承载能力,加之增强颗粒/基体间界面良好的结合,使SiC颗粒的添加提高了复合材料的磨损抗力.同时,促进了富铁机械转移层的形成,降低了摩擦系数和磨损率.AA6061基体和强化材料在20 N载荷下的磨损机制均为磨粒磨损.关键词:干滑动磨损;AA6061;纳米SiC强化;磨粒磨损;......
