      abstract     = {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, as these alloys show improved corrosion resistance
                      and higher operating temperatures compared to Ni-base
                      superalloys. Those blades are often protected by a thermal
                      barrier coating system (TBC) consisting of a metallic bond
                      coat for corrosion and oxidation resistance 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 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. It was
                      found, that interdiffusion leads to dissolving of the
                      γ`-phase in the superalloy and formation of various W-rich
                      phases.},
