摘要: 通过电子束物理气相沉积的方法在TC4基体上制备ZrO2涂层,探究其对基底阻尼作用的影响机理.通过SEM和XRD对涂层的表面形貌和结构特性进行表征,并利用动态力学分析仪(DMA)检测涂层的阻尼性能.结果表明:随着基体温度的升高,晶粒尺寸变大,微缺陷减小,薄层损耗因子产生混合取向,损耗因子增加,阻尼性能提高.在高频下,由于补偿效果,涂层中混晶取向的晶界缺陷消失,阻碍了涂层阻尼性能进一步提高.基底温度为400℃, 激振频率为55Hz时阻尼性能最好.

Abstract: The ZrO2 coatings were deposited onto TC4 substrate by electron beam physical vapor deposition to explore the mechanism of its effect on the damping of the substrate. The surface morphology and structural properties of the coatings were characterized by SEM and XRD, while the damping properties of the coatings were measured using the dynamic mechanical analyzer(DMA). The results showed that, with the temperature increasing, the grain size becomes larger, the micro-defects decrease, the thin layer loss factor produces a hybrid orientation, the loss factor increases, and the damping performance improves. At high frequencies, due to the compensation effect, the grain boundaries defects of the mixed crystal orientation in the coating disappear, which hinders the further improvement of the damping characteristics of the coating. The damping performance is the best when the substrate temperature is 400℃ and the frequency is 55Hz.
