Abstract

The previously developed cyclic thermogravimetry analysis (CTGA) method is applied to the cyclic oxidation at 1100 °C of ZrO2–Y2O3/NiPtAl or NiCoCrAlYTa/single crystal nickel-base AM3 superalloy TBC systems. Cyclic thermogravimetry with fast heating and cooling and high accuracy in mass measurement allows to measure oxidation kinetics of the bond coating and also to detect and quantify the occurrence of the top coating cracking and spalling. The resulting data could be used later on, for time of life modelling of TBC systems.
