摘要
采用原位反应合成法制备出TiB2颗粒增强铝基复合材料。利用MMW-1型摩擦实验机,在不同载荷和转速下,测试不同成分原位生成的TiB2增强铝基复合材料在室温下的摩擦磨损性能变化情况;并用扫描电镜分析技术进行辅助研究。结果表明,TiB2颗粒增强铝基复合材料的摩擦磨损性能在很大程度上得到改善;实验过程在摩擦磨损表面出现大规模的"犁沟",属于磨粒磨损。
Aluminium matrix composites reinforced with particulates Of TiB2 were in-situ synthesized. Using MMW-1 friction test instrument, the friction and wear behaviour of the composites in room temperature was investigated under various loads and rotary speeds. Scanning electron microscopy is used for supporting analysis. The results show that the properties of friction and wear of the composites are improved compared with aluminum alloy. The wear mechanism is abrasive wear because a large of furrows appear in the surface of friction and wear.
