颗粒增强铝基复合材料由于性能优良,成本比纤维增强铝基复合材料低得多,近年来已经成为人们研究的热点。石墨颗粒的加入能显著提高材料的耐磨、减摩和自润滑性能,能大大改善材料的吸震性和发削加工性能,能降低材料的膨胀系数,因此它适用于制造活塞、缸套、轴瓦、衬套等耐磨件, Particulate reinforced aluminum matrix composites have become the hotspot of research in recent years because of their excellent properties and lower cost than fiber reinforced aluminum matrix composites. The addition of graphite particles can significantly improve the material’s wear resistance, friction reduction and self-lubricating properties, can greatly improve the material’s shock absorption and shaving performance, can reduce the material’s expansion coefficient, so it is suitable for manufacturing piston, cylinder liner, bush , Bushings and other wear parts,
