Abstract
This chapter gives an overview on integrative, through-process modeling and simulation approach for coated turbine blades on different scales. The approach includes the modeling of the production, materials properties, and in-service degradation processes and is accompanied by the actual production and testing of coated CMSX-4 single-crystal turbine blades and laboratory specimens. Especially, solidification of the blade alloy during casting, microstructural changes during homogenization and aging heat treatments, chemical vapor deposition of an Al2O3 diffusion barrier coating, physical vapor deposition (sputtering) of a (Ni,Co)CrAlY bond coat, atmospheric plasma spraying of a Y2O3 stabilized ZrO2 thermal barrier coating, microstructural changes, and development of critical stresses under in-service conditions are addressed.
