It is found that the oxygen can difficultly diffuse through the sealing top coat irradiated by HIPIB, causing that the oxidation resistance of the irradiated TBCs is better than that of the as-deposited TBCs due to the decrease of oxygen activity near the interface between the top coat and the bond coat.

经辐照样，陶瓷层顶层形成微米厚致密封顶层，使氧难以穿透陶瓷层，导致陶瓷层/粘结层界面氧的活性降低，从而降低了粘结层氧化速率，使辐照样抗氧化性能优于原始EB-PVD热障涂层。
