Effects of Atomic Layer Deposition-Alumina on Moisture Resistance Properties of Yttria-Stabilized Zirconia Thermal Barrier Coatings in Hydrogen Enriched Flame

Ziyang Shen, Rıdvan Küçükosman, Bao Yang, Ashwani Kumar Gupta

Abstract Current thermal barrier coatings (TBCs), typically made of yttria-stabilized zirconia (YSZ), face challenges in the high-moisture, high-temperature environment during the combustion of hydrogen-enriched fuels. This is mainly due to YSZ's high ionic conductivity facilitating moisture transfer through the YSZ layer toward …
