Abstract:In this study, the 5%vol.Ti3SiC2/Al composites were successfully fabricated by the Spark Plasma Sintering technology. The effects of sintering temperature and time on the microstructure and properties of the composites were investigated. The results show that Ti3SiC2 particles did not decompose significantly during the preparation process and there was no significant evidence of interfacial reaction between Ti3SiC2 and Al matrix, and the shape of reinforcing particles was complete which distributed uniformly on the matrix grain boundaries.

When the samples sintered at 600℃ and stayed 10min, the density of composites hit to 96.6% and Vickers Hardness reached to 38, stable friction coefficient was about 0.3 and wear amount was 0.32 × 10-2g.
