摘要

The aim of the present work was to prepare Ti₃SiC₂-SiC composite by using liquid silicon infiltration (LSI) from TiC/C preform. XRD, SEM and EDS were used to identify the formed phases and analyze the microstructures of the obtained composites. The results show that the composites are made of Ti₃SiC₂ and small SiC. The surface morphologies of Ti₃SiC₂ exhibit plate-like structure with the grain size of 3-10um. The hardness of S1550-1, S1550-3 and S1550-4 is 6.8GPa, 7.1GPa and 7.8GPa for a load of 10kg, respectively. Their density is in the range of 3.55-3.96g/cm³. All the experimental results prove that the novel in situ synthesis route of Ti₃SiC₂-SiC composite by LSI is feasible.
