摘要
利用搅拌熔铸法将废弃玻璃颗粒加入到熔融的基体合金ZL10 5中 ,制备出了废弃玻璃 /铝基复合材料。研究了复合材料的微观组织、力学性能及断裂机理。结果表明 ,玻璃颗粒较均匀地分布于基体中 ,与基体发生界面反应 ;与基体合金相比 ,废弃玻璃颗粒的加入提高了复合材料的硬度和抗拉强度 ;在低载荷下 ,复合材料的摩擦性能优于基体合金。由于玻璃颗粒形状较尖锐 ,尺寸大小不均 ,并存在加工缺陷 。
Waste glass particles were successfully introduced into aluminum base alloy (ZL105) melts as reinforcement to produce glass particle reinforced Al composites through vortex method. The microstructures, mechanical properties and fracture mechanism were investigated. It was found that the waste glass particles are distributed uniformly in matrix alloy. There is interfacial reaction at interface between glass particle and matrix alloy. Compared with matrix alloy, the mechanical properties of composites are improved due to the incorporation of waste glass particles. Dispersion of glass particle in the matrix increases their resistance to wear under low load.
