Fatigue cracks in a thermal barrier coating system on a superalloy in multiaxial thermomechanical testing
Bartsch, Marion; Baufeld, Bernd; Dalkilic, S.; Chernova, L.; Heinzelmann, Michael (Elsevier Sci LTD, 2008)Thermal barrier coatings (TBC,) are applied on cooled gas turbine components. Between the heated and cooled surfaces a thermal gradient develops, resulting for constraint components in high multiaxial stresses, which may ... -
Multiaxial thermo-mechanical fatigue on material systems for gas turbines
Bartsch, Marion; Baufeld, Bernd; Heinzelmann, M.; Karlsson, A. M.; Dalkilic, S.; Chernova, L. (Wiley-V C H Verlag GMBH, 2007)Material systems made from nickel based superalloys with protective coatings have been tested in thermo-mechanical fatigue with superposed thermal gradients, which generated multiaxial stress states. The testing conditions ... -
The role of cyclic mechanical loading and thermal gradients in damage behavior of thermal barrier coating systems
Ceramic thermal barrier coatings (TBC) can exhibit premature in-service failure due to spallation as a consequence of exposure to elevated temperatures, aggressive environments, and cyclic thermal and mechanical loading. ... -
Testing and characterization of ceramic thermal barrier coatings
Bartsch, Marion; Baufeld, Bernd; Dalkilic, S; Mircea, I (Trans Tech Publications LTD, 2005)This paper gives a short overview of tests applied for the investigation of long term behaviour of thermal barrier coating systems. A variety of tests has been conducted on an exemplary material system with the coatings ... -
Time-economic lifetime assessment for high performance thermal barrier coating systems
Bartsch, Marion; Baufeld, Bernd; Dalkilic, S.; Mircea, I.; Lambrinou, K.; Leist, T.; Karlsson, A. M. (Trans Tech Publications LTD, 2007)Strategies for time-economic lifetime assessment of thermal barrier coatings (TBC) in service are described and discussed on the basis of experimental results, achieved on material systems with coatings applied by electron ...
