Effects of the chemistry of coating and substrate on the steam oxidation kinetics of environmental barrier coatings for ceramic matrix composites

K. N. Lee et al.

Summary: NASA improved the lifespan of EBCs by modifying the chemistry of Gen 2 EBC, leading to a reduction in TGO thickness. Researchers also found correlations between the chemistry of EBC and CMC, and the growth rates of TGO.

Perspectives on Environmental Barrier Coatings (EBCs) Manufactured via Air Plasma Spray (APS) on Ceramic Matrix Composites (CMCs): A Tutorial Paper

Kang N. Lee et al.

Summary: The literature contains numerous information on the significant achievements in aerospace gas turbine engines through the use of CMCs and EBCs in their hot zones. These achievements include weight reduction, lower fuel consumption, higher operation temperatures, superior thrust-to-weight ratio, and decreased emission of toxic gases. However, it is often unclear to readers how these achievements are realized together.
