1. Introduction. Thermal barrier coatings (TBCs) based on 7−8 wt. yttria stabilized zirconia (7-8YSZ) which have both excellent mechanical and thermal properties are the most reliable recipe applied in jet engines and ground turbines .The durability of TBCs depends on the strain tolerance of ceramic coatings and the resistance to crack nucleation and propagation at the interface.
