摘　　要：通过YSZ膜料的制备及结构分析,得出Y2O3的最佳加入量。结果表明Y2O3的加入量达到7 mol%时,材料中Zr O2主要以高温相存在,达到了材料稳定的要求;通过对YSZ膜料和薄膜的结构检测和晶粒尺寸计算,进一步证明Y2O3对Zr O2具有良好的稳定作用;提出膜料预熔是一次高温退火过程,能使未完全发生相变的单斜相Zr O2转变为高温相。By preparation and structural analysis of Y2O3 stabilized Zr O2（YSZ） coating material, the optimum content of Y2O3 are obtained. The result indicates the Zr O2 material changes from a monoclinic phase to high temperature phase with increasing Y2O3 mole content to 7%. Structure test and grain size calculation of the YSZ coating material and thin film proves that Y2O3 has a good stabilized effect on Zr O2. Moreover, we also bring forward that premelting of the coating material is a high temperature annealing process, and it is helpful for Zr O2 material to change from monoclinic to high temperature phase.
