Thermal Barrier Coatings (TBCs) are used to protect turbine blades in the SNECMA-M88 aeroengine. A bondcoat (NiAl-Pt) lies between the substrate, a single crystal superalloy and a ceramic layer (EBPVD ZrO2-7% Y2O3).The bondcoat rheology has been studied in the brittle and the viscoplastic domains and a fatigue failure criterion has been established and applied to the thermal fatigue behaviour.The study of the whole TBC is focussed on its interfacial resistance after annealing at 1373K, its behaviour under low cycle fatigue at 1373K and thermal-mechanical fatigue between 373K and 1373K. Annealing at 1373K of adhoc samples, followed by a monotonic tensile test at RT led to cohesive delamination of the interface between the aluminaforming bond...
