AB  - In this poster the interaction of vacuum plasma-sprayed (VPS) protective bond coats and γ/γ`-strengthened Co-base superalloys during thermal treatment is presented. γ/γ`-strengthened Co-base superalloys are currently investigated with the aim of utilizing them for high-temperature, high-load applications in gas turbine blades. Those blades are always protected by a thermal barrier coating system (TBC) consisting of an oxidation-resistant metallic bond coat and a ceramic top coat. Plasma-sprayed MCrAlY bond coats (M=Co,Ni) are commonly used for this application. For the new Co-base superalloys the interaction with the adjacent bond coat needs to be studied to ensure their compatibility. To do this, MCrAlY-coated single-crystal and polycrystalline Co-base superalloy samples were thermally treated at 900 °C and analysed using SEM and EDX. In this work current results are presented with an emphasis on the interdiffusion behaviour. Phases formed in the interdiffusion zone are identified and analysed.
