Notes:
Thermally grown oxide (TGO) spallation increases the degradation rate of aluminideprotective coatings during thermomechanical cycling. Thermal expansion misfit between TGO,bond coat and substrate, applied mechanical load in the system, and local instabilities are knowntriggers for spallation. Mechanical tests have been performed on coated and oxidised AM1superalloy. In situ and post mortem study including digital image analysis and SEM wereperformed in order to characterise strain fields and associated damage field. Good correlation isfound between oxide strain and damage extent
