Three commercial production electron beam physical vapor deposited thermal barrier coatings (TBCs) were non-destructively examined as a function of furnace thermal cycling test by using photostimulated luminescence spectroscopy (PSLS). The TBCs specimens consisted of: 350um thick YSZ and 200um thick shot-peen NiCoCrAlY bond coat on CM247; 145um thick YSZ and 50um thick as-coated (Ni,Pt)Al bond coat on CMSX4; and 140um thick YSZ and 30um thick grit-blasted (Ni,Pt)Al bond coat on Rene‘N5 substrate. Each thermal cycle during the furnace test consisted of a 10 minute heat-up, 1 hour dwell at 1121°C, and a 10 minute forced air-quench. Trends in the photostimulated luminescence were examined and the compressive residual stress within the thermally grown oxide (alpha-Al2O3) was determined based on piezospectroscopic shifts as a function of thermal cycling with respect to lifetime-remain assessment. Distinctive observations made by PSLS were correlated to microstructural development, damage initiation and failure characteristicsdifferent for each TBC system.
