The three-dimensional structure of thermal barrier coatings has an important effect on its performance. Thermal barrier coatings prepared by electron beam physical vapor deposition (EB-PVD) was investigated, and a hightemperature oxidation experiment at 1050℃ was carried out, three-dimensional(3D) imaging were performed by micro- CT and focused ion beam-scanning electron microscopy, and the three-dimensional structure of EB-PVD thermal barrier coatings was obtained. Three-dimensional distribution of thermally grown oxide, inter-diffusion zone, pores, microcracks were obtained, and the thickness of TGO and micro-cracks were quantitatively analyzed. The results show that the TGO thickness analyzed by micro-CT and FIB-SEM are consistent with SEM results, the average depth of microcracks is 0.14 μm, and the micro-cracks only can be observed by a higher resolution micro-CT.
