SiC和石墨颗粒混杂增强铜基复合材料的摩擦磨损性能
Friction and Wear Properties of Cu Matrix Composites Hybrid Reinforced with SiC and Graphite Particles
摘 要
采用粉末冶金方法制备了SiC和石墨混杂增强铜基复合材料,研究了该复合材料在不同载荷条件下的摩擦磨损性能,并通过观察磨损表面形貌,研究其磨损机理.结果表明:在摩擦过程中,SiC颗粒作为载荷的主要承载单元,起到了较好的硬质承载支点的作用,石墨颗粒则发挥了较好的自润滑减摩效果,二者协同作用明显提高了铜基复合材料的耐磨性;该复合材料的磨损机理主要以磨粒磨损为主.

Abstract
SiC and Graphite hybrid reinforced copper matrix composites were prepared by power metallurgy method.The friction and wear properties of the composite under different loads were studied,and then the wear mechanism was analyzed through observation of worn surface morphology.The results show that during the friction process,SiC particles played a good role in hard bearing as the main bearing fulcrum and graphite particles can result in a self-lubrication antifriction.The synergistic effect of SiC particles and graphite particles improved the wear resistance of the composite.Abrasive wear was the main wear mechanism of the composite.
