Layer analysis of coating performance

© Fraunhofer IWM

The operational behavior of layers is largely determined by the deposition conditions during application and the resultant material properties such as chemical composition, microstructure and stress state. Material compositions are characterized in their relationship to depth using optical glow discharge spectroscopy. Temperature-dependent residual stress states in the layers are identified via a heated interferometer. The analyses enable us to identify failure mechanisms and optimize coating processes.
