Thermal Barrier Coatings for greener heat-to-power applications: understanding limits of operation under hydrogen combustion and sustainable outlook - TBC4H2

Project summary

Increasing the efficiency and lowering the CO2 and NOx emissions of aircraft and industrial turbines requires raising their operational temperature which is currently limited by the materials used for their components. The application of hydrogen-based fuels will contribute to new degradation modes of materials related to water vapor presence in the exhaust gases. The goal of the project is to gain new knowledge on the high temperature behavior of TBCs on Ni-based superalloys for turbines components operating at temperatures beyond the capabilities of currently used materials (1200 °C) and under water vapor atmospheres (hydrogen combustion). The results of the project will strengthen the development of technologies applied in aviation and power generation for protection against high temperature of turbine blades operating under harsh environments. The project is in line with the Green Deal policy assuming a significant reduction of CO2 emissions by the transport sector by 2050.
