Abstract: A series of YSZ coatings were deposited by electron beam evaporation coating. The thermal shock test of the coatings was used to test the peeling of different process coatings under the same thermal shock times. It was found that the thermal shock performance of the coating was best at 350 mA. Discussion on the failure mechanism of the coating shows that the dense coating structure hinders the alleviation of thermal stress, the loose coating structure accelerates the infiltration of oxygen, and accelerates the growth of TGO, which results in the failure of coating.

Key words: EB-PVD, TBC, thermal shock performance, failure investigation
