AI Technical Summary
Implementing ceramic matrix composite (CMC) materials in airfoils of gas turbine engines faces challenges due to unique issues related to mechanical support and thermal protection, particularly in high-temperature environments, where the support structures made of metallic materials are susceptible to excessive heating and oxidation.
A thermal barrier coating (TBC) is applied to the metallic support structures, such as spar pieces, to enhance their heat resistance and oxidation resistance, while ensuring the sealing surfaces remain free of the coating to maintain effective sealing, thereby reducing cooling requirements and minimizing the risk of damage.
The TBC improves the ability of support structures to withstand high temperatures, reduces cooling air requirements, and enhances the overall cooling efficiency of the engine by preventing excessive heating and oxidation of metallic components.
