As one of promising thermal barrier coating (TBC) candidates, La2Ce2O7 (LC) has attracted increasing attention because of its low thermal conductivity and potential capability to be operated above 1250°C. In this paper, the microstructure evolution and mechanical properties of the plasma-sprayed LC...
