 Thermal barrier coatings perform the important function of insulating components.

Thermal barrier coatings (TBCs) are necessary for insulating components that operate at high temperatures, such as gas turbine and aeroengine parts. Turbine blades, combustor cans, ducting, and nozzle guiding vanes are all examples. The use of TBCs has allowed gas turbines to operate at higher temperatures.


When subjected to heat flow, TBCs have a relatively low thermal conductivity, resulting in a huge temperature difference in the coating. Yttria stabilised zirconia (YSZ) is the most commonly used Thermal Barrier Coatings material, with thermal shock and thermal fatigue resistance up to 1150°C. Plasma spraying and electron beam physical vapour deposition (EBPVD) are the most used methods for depositing YSZ. It can also be deposited by HVOF spraying for applications like blade tip wear prevention, where the material's wear resistance qualities can be employed.
