Gas turbine engines operate under the conditions of high temperature and stresses, and the engine components are also subjected to corrosion, oxidation and abrasion. Ceramic Thermal barrier coatings (TBCs) when deposited onto the hot sections of turbine engines improve their performance. TBCs have porosity by design, the architecture of which depends on the processing route. The presence of porosity gives rise to its low thermal conductivity and high strain tolerance. The porosity and its architecture can be significantly affected in service, thus changing the properties of the TBC and hence...
