Einfluss der Bondcoatzusammensetzung und Herstellungsparameter auf die Lebensdauer von Wärmedämmschichten bei zyklischer Temperaturbelastung
In the present study the influence of the bond coat composition on the lifetime of thermal barrier coatings during thermal cycling was investigated. The knowledge, that the reactive elements (RE), which are essential for the improvement of the oxide scale adhesion, are “lost”, during the bond coat …

A small-angle scattering analysis of the influence of manufacture and thermal induced morphological changes on the thermal conductivity of EB-PVD PYSZ thermal barrier coatings
Die Abscheidung von elektronenstrahlaufgedampften Wärmedämmschichten (EB-PVD WDS) auf metallischen Turbinenschaufeln von Triebwerken führt zu einer Verbesserung der Schaufelinnenkühlung, d.h. die Eintrittstemperatur der Gase in der Turbine kann erhöht werden und somit die Effizienz des Triebwerks …

Failure mechanisms of thermal barrier coatings for high temperature gas turbine components under cyclic thermal loading
The mechanical behavior of PYSZ TBCs, deposited by EB-PVD and APS techniques, has been studied under thermal cyclic and isothermal loading. Two types of bond coats were chosen for the different multilayer systems: a single phase (Ni,Pt)-aluminide and a NiCoCrAlY overlay layer in the case of the …
