摘要：
The Ti3SiC2/Cu composites were prepared by spark plasma sintering (SPS) process using Ti3SiC2 ceramic powder and Cu powder as raw materials. The effect of content of Ti3SiC2 and sintering temperature on the microstructure, relative density and hardness of Ti3SiC2/Cu composites were investigated, and the friction and wear properties of the Ti3SiC2/Cu composites after SPS were also studied. The results show that Ti3SiC2 are evenly distributed in Cu matrix for the Ti3SiC2/Cu composites prepared by SPS process. But with the increase of Ti3SiC2 content and sintering temperature, agglomeration trend appears in the tissue, and some Ti3SiC2 and Cu miscibility at the interface enhances the ability to bind to the matrix. The Ti3SiC2 content and sintering temperature have a great influence on the density and microhardness of the Ti3SiC2/Cu composites. When the sintering temperature is 900℃, the density of the Ti3SiC2/Cu composites reaches 99.7%, which is close to complete density. The hardness of the Ti3SiC2/Cu composites is about 2 times higher than that of pure Cu. The wear mechanism of Ti3SiC2/Cu composites with different Ti3SiC2 contents is also different. When the content of Ti3SiC2is low (1vol%-5vol%), the wear mechanism is abrasive wear and adhesive wear. With the increase of Ti3SiC2 content (10vol%-15vol%), it gives play to its self-lubricity, the friction and wear properties of the Ti3SiC2/Cu composites are improved, and the wear mechanism is changed to plough cutting and slight adhesive wear. With the content of Ti3SiC2 further increases to 20vol%, the wear surface becomes uniform and flat, indicating that the wear resistance of the Ti3SiC2/Cu composites is enhanced.
