摘要
本文研究了复合电沉积法制备的α-Al2O3/Cu复合材料的性能和磨损特征,测定了Al2O3粒径在0.5~5μm,含量在4~16%时Al2O3/Cu复合镀层的硬度和磨损率,用扫描电镜对磨损形貌进行了分析,并对其磨损机制进行了探讨。结果表明,镀层中硬度随Al2O3含量增加呈线性增长,且含大颗粒Al2O3镀层的硬度略高于小颗粒镀层,Al2O3颗粒含量和粒径大小对磨损率和磨损机制有显著影响。
The properties and wear characteristic of Al 2O 3 particles reinforced copper composite by electrodeposit have been investigated, and their hardness and wearability were tested in the range of 0.5 to 5.0μm particles size and 4 to 16vol% content. The results show that the coating hardness increases linearly with Al 2O 3 content, and the coating with large Al 2O 3 particles is slightly harder than the one with smaller particles. The content and the size of Al 2O 3 particles have great effects on the wearability and wear mechanism of the composites.
