| 摘 要： | 采用无机盐先驱体 ,溶胶 -凝胶工艺在氧化铝基工程陶瓷上成功制备了ZrO2 涂层。用差热分析(DTA)、扫描电子显微镜 (SEM)、X射线衍射 (XRD)等分析手段对ZrO2 涂层的物相组成、表面和断面形貌进行了表征。对精磨、热处理、ZrO2 涂层试样的抗弯强度和Weibull模数进行了比较。结果表明 :ZrO2 涂层可以明显改善陶瓷的表面质量 ;涂层与基体结合紧密 ,无明显的界面层 ;涂层试样的抗弯强度和Weibull模数均比未涂层试样有明显的提高。 |
| 关 键 词： | 溶胶-凝胶工艺 ZrO2涂层 抗弯强度 Weibull模数 |

| Abstract: | ZrO 2 coating was prepared on alumina engineering ceramics.The composition,surface and cross-section apppearances were characterized by DTA,SEM and XRD.The bending strength and the Weibull modulus of the samples after finishing grinding,heat treatment and coating with ZrO 2 film were compared.The results showed that the ZrO 2 coating improved the surface quality evidently.The cohesion of the coating and substrate was compact without distinct imterface.The coated samples had the bigger bending strength and the Weibull modulus. |
| Keywords: | sol-gel ZrO 2 coating bending strength Weibull modulus |
