本研究采用铸造或粉末冶金法制备了Al基al2o3和SiC颗粒增强复合材料。在针盘式磨损试验台上，以10N载荷和50rpm转速在干燥条件下对复合材料的摩擦学性能进行了研究。对其力学性能进行了研究。研究了增强材料对摩擦磨损性能和力学性能的影响。此外，用光学显微镜和扫描电镜对材料的微观结构进行了研究。在复合材料中加入颗粒增强铝，可显著提高复合材料的摩擦学性能和硬度。
In this study, Al based Al2O3and SiC particle reinforced composite materials were manufactured by casting or P/M method. Tribological properties of these composite materials were investigated by wearing with 10N load and 50rpm on a pin-on-disc wear test rig at dry conditions. Mechanical properties were investigated. The effects of reinforce materials on tribological and mechanical properties were investigated. In addition to that microstructure of these materials were investigated by optical and SEM microscope. Tribological and hardness properties of composites significantly improved by the use of particle reinforced into Al.
