不同TiB2含量下多元混杂铜基复合材料的摩擦磨损性能
Friction and Wear Properties of Multi-Component Hybrid Cu-Based Composites with Different TiB2 Contents
摘要
Abstract
To clarify the influence of TiB2 on the damage mechanism of hybrid Cu-based composites,the graphite-TiB2 hybrid reinforced Cu-based composites were prepared through rapid vacuum hot pressing sintering method.The effect of TiB2 content(0.5%,1.0%,1.5%and 3.0%,mass fraction)on friction coefficient,wear rate and wear surface morphology of the composites was analyzed.The results show that with the increase of TiB2 content,the friction coefficient and wear rate initially decrease and then increase,and the wear resistance of the composites with 1.0%TiB2 is better,the wear mechanism is mainly abrasive wear,accompanied by adhesive wear and oxidative wear.The worn surface of the hybrid Cu-based composites is composed of graphite,CuO,Fe3O4 and Fe2O3 phases.关键词
