Ermittlung des Verformungs- und Schädigungsverhaltens von Wärmedämmschichtsystemen
The application of gas turbines for the generation of electricity has significantly increased over the past decades. In order to reduce emissions and to conserve fossil fuels, the thermal efficiency of stationary gas turbines should be increased. This can be achieved mainly by higher turbine inlet …

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 …

Effect of thermal and mechanical loadings on the degradation and failure modes of APS TBCs
Thermal barrier coatings (TBCs) are applied for the thermal protection of hot section components of gas turbines to improve their life-time or to raise the power and thermal efficiency of the gas turbine by increasing the turbine inlet temperature. TBCs limit the lifetime of the coated component …
