Thermal barrier coatings (TBCs) are used to protect the hot sections of gas turbines and jet engines. A typical TBC system consists of a substrate, bond coat, and a TBC top coat (TC). To develop a high-performance TBC, it is essential to accurately evaluate the residual stress evolution during the t...
