TiC/Cu复合材料的摩擦性能研究

Research on friction performance of TiC/Cu composites

为提高TiC/Cu复合材料的摩擦性能,对不同TiC掺量条件下TiC/Cu复合材料的摩擦磨损性能进行实验分析。结果表明,与基体试样相比,复合材料的磨损系数较低,且在低载荷磨损时磨损性能更佳,当TiC含量增加到3%时摩擦系数最低。通过磨损形貌分析发现,基体材料主要为黏着磨损,复合材料的磨损行为表现为氧化、黏着和剥层磨损,且复合材料中的TiC颗粒具有很好的抵抗黏着磨损的作用,使得复合材料表面磨损程度减轻。

In order to improve the friction properties of TiC/Cu composite,the friction and wear properties of TiC/Cu composites with different TiC content are tested and analyzed.The results show that the wear coefficient of the composite is lower than that of the matrix,and the wear performance is better at low load wear and the friction coefficient is the lowest when the content of TiC is increased to 3%.Through the wear morphology analysis,it is found that the matrix material is mainly adhesive wear,and the wear behavior of the composites is oxidized,adhesive and stripped,and the TiC particles in the composite can resist the adhesion and wear,thus the wear surface of the composites is reduced.
