This paper describes a through-process modelling on a microstructural level of the production of a coated turbine blade, including its in-service properties and degradation, accompanied by the actual production and testing of a CMSX-4 single crystal turbine blade dummy. The following steps are dealt with by modelling and experiment: solidification of the blade alloy during casting, microstructural changes during homogenization and aging heat treatments, chemical vapour deposition of an Al(2)O(3) diffusion barrier coating, physical vapour deposition (sputtering) of a (Ni,Co)CrAlY bond coat, atmospheric plasma spraying of an Y(2)O(3) stabilized ZrO(2) thermal barrier coating and microstructural changes and development of critical stresses at in-service conditions. This work forms a part of the Collaborative Research Centre 370 (SFB370) "Integrative materials modelling".
