Abstract
The La2Ce2O7/8YSZ double-ceramic-layer thermal barrier coatings (TBCs) system, which is prepared by atmospheric plasma spraying (APS), is found to have a much longer lifetime compared with the single layer La2Ce2O7 system under the burner rig test. The double-ceramic-layer coating structure design can effectively alleviate the thermal expansion mismatch between the La2Ce2O7 coating and the bondcoat. The failure mechanism of the La2Ce2O7/8YSZ double-ceramic-layer coating is mainly due to the sintering of the La2Ce2O7 coating surface during thermal cycling.
