Title
Thermal Wave Imaging Application In Thermal Barrier Coatings
Abstract
Thermal wave imaging (TWI) is a promising non-destructive evaluation (NDE) technique for life assessment and health monitoring of thermal barrier coatings (TBCs) extensively used for advanced gas turbine engines. In this study, 9 specimens of air plasma sprayed (APS) TBCs were thermally cycled to a peak temperature of 1150°C (2100°F) with dwell time of 10 hours. During thermal cyclic oxidation, TBC specimens were periodically evaluated non-destructively with TWI, and selected specimens were removed from thermal cycling for microstructural analysis by scanning electron microscopy (SEM). Results from TWI were correlated to the microstructural development in APS TBCs. TWI enabled the detection of subsurface damage initiation and progression in APS TBCs.
