摘要:

采用分子级混合方法及SPS烧结技术制备了Ti3C2Tx含量分别为5vol%、10vol%和20vol%的Cu/Ti3C2Tx复合材料, 研究了Ti3C2Tx含量对铜基复合材料的导电性、力学性能及摩擦磨损性能的影响。研究发现: 随Ti3C2Tx含量增加, Cu/Ti3C2Tx复合材料的相对密度及电导率均持续下降, 拉伸强度则先升高后下降; 当Ti3C2Tx含量为5vol%时, Cu/Ti3C2Tx复合材料的拉伸强度相比纯铜提高了43%。添加Ti3C2Tx可以明显改善Cu/Ti3C2Tx复合材料的摩擦磨损性能, 当Ti3C2Tx含量为10vol%时, Cu/Ti3C2Tx复合材料的磨损率仅为2.55×10-7 mm3/(N·m), 比纯铜降低了一个数量级。

Abstract:

Cu/Ti3C2Tx composites with Ti3C2Tx content of 5vol%, 10vol% and 20vol% were prepared by using a molecular-level mixing process and spark plasma sintering (SPS). Influence of Ti3C2Tx content on electrical, mechanical and tribological properties was investigated. The result showed that relative density and electrical conductivity of Cu/Ti3C2Tx composites gradually decreased with the Ti3C2Tx content increase, while the tensile strength of Cu/Ti3C2Tx composites increased at first and then decreased. When the Ti3C2Tx content was 5vol%, the tensile strength of Cu/ Ti3C2Tx composites increased by 43% than that of pure copper. Tribological properties of Cu/ Ti3C2Tx composites were enhanced by the addition of Ti3C2Tx. When the Ti3C2Tx content was 10vol%, the wear rate of Cu/ Ti3C2Tx composites was 2.55×10-7 mm3/(N·m), which was one magnitude lower than that of pure copper.

Key words: Ti3C2Tx, copper matrix composites, electrical conductivity, friction and wear
