采用无机盐先驱体，溶胶－凝胶工艺在氧化铝基工程陶瓷基体上成功制备了Ａｌ_２Ｏ_３－ＺｒＯ_２徐层．扫描电子显微镜、Ｘ射线衍射、二次离子质谱分析表明：涂层完整，晶粒均匀，主要成份为α－Ａｌ_２Ｏ_３和ｔ－ＺｒＯ_２；徐层与基体结合紧密，两者存在着明显的元素扩散．

Al₂O₃-ZrO₂ coating was prepared on alumina based engineering ceramics by using inorganic salt as precursors. The results of SEM, XRD and Secondary Ion Mass Spectrometry (SIMS) show that the coating exhibits the complete morphology with the homogeneous crystal grain. In addition, The coating is mainly composed of a-Al₂O₃and t-ZrO₂ after heat treatment at 1100 ℃ for 1h. The coating and substrate adheres each other compactly with distinct interdiffusion near the interface.
