摘要

Thermal Barrier Coatings (TBCs) are widely applied to the blade of aero-engine to effectively prevent them from high-temperature oxidation. This work obtained the real TC/TGO interface topography accurately by using threshold image processing technology, and established the TGO growth control equation based on oxygen diffusion distribution. Results showed that the non-uniform growth and thickening of TGO significantly affect the stress distribution and failure behavior of the TBCs during thermal cycling test. Besides, the effect of the non-uniform growth of TGO on the crack initiation of TBCs was discussed in detail.
