Thermal Barrier Coatings (TBCs) allow the parent metal to operate cooler.
TBCs are characterized by their very low thermal conductivity.
Thermal barrier coatings perform the important function of insulating components, such as gas turbine and aero- engine parts, operating at elevated temperature (e.g turbine blades, combustor cans, ducting and nozzle guide vanes
One of the most common uses of Thermal barrier coatings is in the combustion sections of aircraft turbine engines
