The effects of TiN additions on microstructures and mechanical properties of Ti(C, N)/NiCr cermets were investigated. Results revealed that the hard phase particles were refined and the morphology of the particles changed from a circular to a polygonal shape by the additions of TiN because of the formation of Ti(C,N) solid solution; With increasing TiN additions, the bonding strength increased to the maximum values at 4%TiN content during low sintering temperature and at 6%TiN content during high sintering temperature, respectively, and then decreased. Hardness changed little when TiN addition was less than 10%, but decreased dramatically when TiN addition exceeded 10%. Fracture photograph showed that trans-granular fracture was the main failure mode because of the good interface bonding strength between binding phase and ceramic hard phase. %K Ti(C %K N)/NiCr %K cermet %K microstructure %K mechanical property
