Advanced cooling scheme and Thermal Barrier Coating (TBC) have been applied to industrial gas turbine hot parts as turbine inlet temperature increasing. TBC is effective method for preventing base metal temperature over heating as well as increasing thermal efficiency of plant by cooling air flow reducing. Good coating quality and high durability in long term operation service of power plant are important to obtain high reliability of TBC. In this study, coating quality evaluation method and durability test method of TBC were examined. As a results, it was confirmed that static bending test and Laser thermal cycling test were useful methods
