The TiC-xNi cermets were prepared by combustion synthesis and densification. The process parameters of TiC-xNi system were optimized by experiments. The optimum process parameters The relative density of the block is about 56% and the pre-pressure P1 is 10MPa. The high pressure P2 during densification is determined to be 16 0MPa and the high pressure dwell time t2 to be 20s. The optimum pressurization time t1
