The use of Thermal Barrier Coatings (=TBC) in gas turbines allows to increase the working temperature and therefore the yield of gas turbines. Conventional TBC's (Y 2 O 3 -stabilised ZrO 2 ) are produced by plasma spraying and , electron beam evaporation. CVD processes for the production of TBC's are under investigation.

Journal of Thermal Spray Technology, 1996
The fundamental driving force for the development of thermal barrier coatings has been the continuing quest for ever higher temperatures in gas turbines. Over the period 1940–1970, the temperature capability of superalloys for gas turbine blades, which is defined in terms of 100 h life at 20000 psi (138 MPa) stress, was increased from approximately ...

Thermal Conductivity of a Zirconia Thermal Barrier Coating
Journal of Thermal Spray Technology, 1998The conductivity of a thermal-barrier coating composed of atmospheric plasma sprayed 8 mass percent yttria partially stabilized zirconia has been measured. This coating was sprayed on a substrate of 410 stainless steel. An absolute, steady-state measurement method was used to measure thermal conductivity from 400 to 800 K.

Latest Advancements in Thermal Barrier Coatings
Canadian Aeronautics and Space Journal, 2004As gas turbine engine designers strive to increase engine efficiency, thrust, and higher turbine inlet temperatures, the substrate superalloys are pushed to their upper limits of thermal stability. For this reason, thermal barrier coatings, with a typical composition of ZrO2-7%Y2O3, were developed and applied to the metallic substrate for added ...

Thermal conductivity of thermal barrier coatings
Materials Science and Engineering: A, 1998Abstract In thermal barrier coatings and other ceramic oxides, heat is conducted by lattice waves, and also by a radiative component which becomes significant at high temperatures. The theory of heat conduction by lattice waves is reviewed in the equipartition limit (above room temperature).
