摘要
借助DSC、SEM分析 ,分别对Ti ZrO2 体系、Ti Al ZrO2 体系、Ti B Al ZrO2 体系中Ti和ZrO2 的界面反应进程及初始反应温度进行了研究。结果发现 :随着Al、B及微量添加剂的加入 ,Ti和ZrO2 的初始反应温度逐步升高 ;Ti Al ZrO2 和Ti B Al ZrO2 体系与Ti ZrO2 体系相比较 ,Ti和ZrO2 初始反应温度分别提高近 5 0℃和70℃ ,从而弱化了Ti和ZrO2
By means of DSC and SEM, the interface reaction process and the initial reaction temperature between Ti and ZrO2 in the Ti-ZrO2, the Ti-Al-ZrO2 and the Ti-B-Al-ZrO2 system have been studies, respectively. The result is that the initial reaction temperatures between Ti and ZrO2 increase gradually with the addition of the Al, B and the microcontent additive. Compared to the Ti-ZrO2 system, the initial reaction temperatures in the Ti-Al-ZrO2 system and the Ti-B-Al-ZrO2 system increase by 50°C and 70°C , and the interface reaction between Ti and ZrO2 mold material is weakened.
