High-Temperature Optical Techniques Development and its Application in Thermal Barrier Coatings

Owing to demanding operating environment and multilayered structure, the experimental characterization of thermal barrier coatings is challenging. Herein, our ongoing work on the high-temperature optical techniques for their deformation and residual stress measurements are reviewed.
