The application of plasma sprayed zirconia thermal barrier coatings in aviation and industrial gas turbines has made great progress, and has been used in the turbine part of gas turbines to a certain extent.
Because this coating can reduce the temperature of air-cooled high-temperature components by 50 to 200 ℃, it can significantly improve the durability of high-temperature components, or allow to increase the gas temperature or reduce the amount of cooling gas required to keep the temperature of the high-temperature components at a constant temperature. Change, thereby improving the efficiency of the engine
