| 摘 要： | 通过热力学数据的预报与计算，对ＺｒＯ_２－Ｔｉ体系的相间热力学稳定性进行了分析，并确定了材料合成的热力学条件．在此基础上常压烧结合成了不同组分配比的ＺｒＯ_２－Ｔｉ系复合材料，并采用ＸＲＤ、ＳＥＭ、ＴＥＭ等方法对材料的显微结构进行了表征．ＺｒＯ_２－Ｔｉ系均质复合材料由α－Ｔｉ相，四方ＺｒＯ_２相和少量的单斜ＺｒＯ_２相组成．ＸＲＤ和ＴＥＭ分析表明，组元Ｔｉ和ＺｒＯ_２之间没有发生明显的化学反应，具有良好的化学相容性．

| Abstract: | The standard Gibbs free energy of Ti_2O was predicted according to the quasi-parabola rule. The co-existing region of Ti and ZrO_2 was obtained by thermodynamic calculation to de termine the synthesis conditions of this composite. ZrO_2-Ti system composites sintered under ordinary pressure were prepared by a powder metallurgical method. The gradient distribution of composition, the interfacial microstructure between layers and the combining state of phases between Ti and ZrO_2 were investigated by means of XRD, SEM, EDS, TEM and so on. The experimental results show that the joint between Ti and ZrO_2 phases is physical in this composite. ZrO_2 mainly exists as a tetragonal phase. |
