Advanced Thermal Barrier Coatings
Yttria Stabilised Zirconia (YSZ) is a conventionally used top coat material for a thermal barrier coating (TBC) system below 1200°C. However, YSZ is not suitable as top coat above 1200°C on account of its sintering effect. Advanced coatings have been developed by the researchers, which would satisfy the need for the mechanical and the thermal properties of the TBCs. The current chapter covers advanced thermal barrier coatings that are suitable for the future generation gas turbines.
