High-Temperature Low-Cycle Fatigue Behaviour of MAR-M247 Coated with Newly Developed Thermal and Environmental Barrier Coating

<div>Degradation of the TEBC system. (a) Delamination of YSZ, <i>ε</i><sub>a</sub> = 0.30%; (b) fatigue cracking and delamination of the mullite + hexacelsian upper layer, <i>ε</i><sub>a</sub> = 0.30%; (c) degradation of TEBC after LCF, <i>ε</i><sub>a</sub> = 0.15%; (d) TGO scale at the YSZ/CoNiCrAlY interface, <i>ε</i><sub>a</sub> = 0.30%.</div>
