Ti(C, N)-304 stainless steel metal cermets were prepared by traditional powder metallurgy and pressureless sintering. The microstructure of metal cermet was analyzed by means of scanning electron microscope, the particle size of hard phase, the bonding degree of hard adjacent phase and the free path of bond phase were analyzed based on stereological principle, and the density and hardness were measured. The effects of sintering temperature and heating rate on the microstructure and properties of Ti(C, N)-304 stainless steel cermets were studied. The results show that the density of cermets increases with the increase of sintering temperature, and cermets cannot be densified at 1 300 ℃ and 1 350 ℃.The average diameter of hard phase particles increases gradually, and the hardness reaches the peak value of HRA 86.3 at 1 450 ℃. The adjacent bonding degree of hard phase decreases gradually, the free path of bonding phase increases gradually, and the hard phase particles are evenly dispersed. The properties of cermets obtained at lower heating rate are better.
