Researches have been conducted on gas turbines for power generation that use carbon-free fuels like hydrogen and ammonia, which do not produce carbon dioxide due to global warming caused by carbon dioxide. In this study, we developed rare-earth element-doped thermal barrier coatings for use on hot parts in the gas turbine. The thermal properties of the developed coatings, including thermal conductivity and thermal fatigue durability, were evaluated and compared to those of conventional yttria-stabilized zirconia thermal barrier coatings. In addition, to assess the applicability of the developed coatings in hydrogen gas turbines, we evaluated the degradation behavior of the coatings in both atmospheric and water vapor environments. This study can provide crucial data for enhancing TBC performance under operation condition of hydrogen gas turbines.
