Ceramic thermal barrier coatings (TBCs) are playing an increasingly critical role in advanced gas turbine engines due to their ability to sustain further increases in operating temperatures. However, these increases in temperature could raise considerable issues associated with increased radiative heat transfer into the TBC systems. This study was conducted to design a ceramic based multiple layered TBC system with high reflectance to radiation. Mathematical modeling was used to calculate the potential temperature reduction on the substrate surface when the multiple layered TBC is applied. The result of the simulation shows that a temperature reduction up to 90 °C is possible when utilizing the designed multiple layered TBC coatings.
