Thermal barrier coating. The key components of the aeroengine are superalloy turbine blades and turbine discs, which are in harsh environments such as high temperature,oxidation and high velocity airflow erosion. For gas turbine components with temperatures up to 1100 ° C, the temperature limit (107...
