If the TBCs system is homogeneous, the TGO will take on relatively regular and periodical undulation. Unfortunately, in actual situation, some abnormal thick areas will be presented in TGO, which is in single-layer or multi-layer form. In SEM, it can be seen that such protrusion areas originate from TGO, and penetrate into bond coat layer gradually with the increment of oxidation time, namely, the oxidation localization phenomenon occurs.
