The role of cyclic mechanical loading and thermal gradients in damage behavior of thermal barrier coating systems
(2005)
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
(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 ...
Fatigue cracks in a thermal barrier coating system on a superalloy in multiaxial thermomechanical testing
(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
(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 ...
Time-economic lifetime assessment for high performance thermal barrier coating systems
(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 ...
