Ti（C,N）-based cermets were prepared by powder metallurgy using TiC,TiN,Mo2C,WC,Co and Ni as raw materials.The effects of Mo2C/（WC+Mo2C） ratio on the microstructure and mechanical properties of Ti（C,N）-based cermets were investigated by XRD,SEM and mechanical properties test.The results show that with the increase of Mo2C/（WC+Mo2C）,the hardness of Ti（C,N）-based cermets increases gradually,and the bending strength decreases first and then increases.At Mo2C/（WC+Mo2C）=0.8,the microstructure of Ti（C,N）-based cermets is refined significantly and the comprehensive mechanical properties are the best,with the Vickers hardness（HV） and bending strength reaching 1 411.15 and 1 053.7 MPa,respectively.
