The method for producing a TiC-ZrC-Ni cermet in which grain growth is suppressed by addition of ZrC according to the present invention is characterized in that (a) TiO 2 powder, ZrO 2 powder and carbon material are first milled to prepare a mixed powder (TiO 2 -ZrO 2- C); (b) heat-treating the mixed powder to produce a composite powder (TiC-ZrC); And (c) secondarily milling the composite powder (TiC-ZrC) and the Ni powder to prepare a mixture. According to the present invention, a high-energy milling process can form a TiC-ZrC type composite powder, instead of forming a powder of (Ti, Zr) C type in which Zr and Ti are solidified in carbide, To produce a TiC-ZrC-Ni cermet. In addition, TiC-ZrC-Ni cermets with excellent mechanical properties can be produced by suppressing the growth of TiC particles by ZrC particles during sintering, and the composite powder (TiC-ZrC) The particle size of the powder is as small as several hundred nanometers and the sintering temperature can be lowered, and the sintering time can also be shortened.
