    摘要:

    以双层结构热障涂层为研究对象,采用三维X射线显微镜、图像处理技术研究了热障涂层的形貌、组成、厚度、孔隙及孔隙率等三维结构特征。采用三维成像方法获得了高分辨率的热障涂层层状结构CT图像,用三维分割与提取法得到了陶瓷隔热层、粘结层和基体的三维形貌,定量分析了厚度、孔隙尺寸、孔隙数量及孔隙率等热障涂层重要表征参数。结果表明,三维X射线显微镜厚度分析结果与扫描电镜分析结果基本一致,孔隙率受重建精度影响。

    Abstract:

    With double-layer structure thermal barrier coatings(TBCs) as the research object, three dimensional(3D) structure characteristics of TBCs such as morphology, composition, thickness, pores and porosity were researched by 3D X-ray microscopy and image processing technique. High resolution CT images of layered structure TBCs were reconstructed by 3D imaging method, 3D morphology of ceramic topcoat, bond coat and substrate were obtained by 3D segmentation and extraction, quantitative analysis of the important characterization parameters of TBCs such as thickness, pore size, pore number and porosity was performed. The results showed that the thickness of TBCs by 3D X-ray microscopy was basically consistent with the results of SEM, and the porosity was affected by the accuracy of the reconstruction.
