【Abstract】 By means of DSC and SEM, the interface reaction process and the initial reaction temperature between Ti and ZrO 2 in the Ti ZrO 2, the Ti Al ZrO 2 and the Ti B Al ZrO 2 system have been studies, respectively. The result is that the initial reaction temperatures between Ti and ZrO 2 increase gradually with the addition of the Al, B and the microcontent additive. Compared to the Ti ZrO 2 system, the initial reaction temperatures in the Ti Al ZrO 2 system and the Ti B Al ZrO 2 system increase by 50℃ and 70℃, and the interface reaction between Ti and ZrO 2 mold material is weakened.更多还原
