Untersuchungen zu den Versagensmechanismen von Wärmedämmschicht-Systemen im Temperaturbereich von 900 C bis 1050 C bei zyklischer Temperaturbelastung
The present work examines the failure mechanisms of TBC-coated systems during cyclic temperature exposure without additional mechanical load in the temperature range between 900°C and 1050°C. If failure appeared until an testing duration of 5000h in the temperature range between 900°C and 950°C, it …

Influence of composition and processing on the oxidation behavior of MCrAlY-coatings for TBC applications
The adherence of the thermally grown oxide (TGO) to the bond coat is recognized to be crucial for the lifetime of thermal barrier coatings (TBC) in aircraft engine and gas turbine blades. The stability of the system has to be guaranteed over extended service times (around 25000h) at high operation …

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 …
