The need for higher efficiencies and performance in gas-turbine engines that propel aircraft
in the air, and generate electricity on land, is pushing the operating temperatures of the …

Abstract About 6‐8 wt% yttria‐stabilized zirconia (YSZ) is the industry standard material for
thermal barrier coatings (TBC). However, it cannot meet the long‐term requirements for …

In this study, corrosion behavior of Yb 2 O 3-Y 2 O 3 co-stabilized ZrO 2 (YbYSZ) was
systematically investigated under CMAS melt attack. The result was found that YbYSZ …

The high-temperature (1500° C) interactions of two promising dense, polycrystalline EBC
ceramics, YAlO 3 (YAP) and γ-Y 2 Si 2 O 7, with a calcia-magnesia-aluminosilicate (CMAS) …

A novel composite-layered thermal barrier coating is designed to solve performance
degradation caused by inevitable thermal exposure. Inspired by cathodic protection with a …

This detailed study compare and contrasts the calcium-magnesium-aluminosilicate (CMAS)
infiltration resistance behavior of electron-beam physical vapor deposition (EB-PVD) …

In this work, the corrosion behavior of Yb 4 Hf 3 O 12 ceramics under CFAS coupled with
water vapor environment at 1400° C for 2–50 h was investigated. Results show that the …

Reactions between silicate deposits and environmental barrier coatings (EBCs) for SiC/SiC
composites can severely degrade coating performance. The goal of the present study is to …

Abstract Calcia-Magnesia-Alumino Silicate (CMAS) is a form of molten siliceous residue
generated at elevated temperatures within aeroengines. CMAS adheres to the surface of …

The chapter describes the different aspects of ceramic materials in gas turbines. The
operation conditions such as high-pressure ratio and high temperatures result in improved …
