Design of CMAS-resistant Gd2O3/YSZ bilayer thermal barrier coatings via apatite phase control

Materials & Design
CaO-MgO-Al2O3-SiO2 (CMAS) corrosion remains a critical challenge for thermal barrier coatings (TBCs) in aero-engines. To address this, we design a novel bilayer TBC system by depositing a Gd2O3 top layer on yttria-stabilized zirconia (YSZ) via ...

Microstructural characterization of GZ/CYSZ thermal barrier coatings after thermal shock and CMAS+hot corrosion test

, 2017
In this study, first, Gd2Zr2O7/ceria–yttria stabilized zirconia (GZ/CYSZ) TBCs having multilayered and functionally graded designs were subjected to thermal shock (TS) test.

An aluminum surface modification strategy for enhancing CMAS corrosion resistance of environmental barrier coatings

Journal of Advanced Ceramics
As the inlet temperature of engines increases, injected sand, volcanic ash, and dust melt to form calcium−magnesium−aluminosilicate (CMAS) glass, which subsequently adheres to the surface of ytterbium monosilicate (YbMS; Yb2SiO5) environmental barrier ...

A quaternary high entropy (Er1/4Sc1/4Tm1/4Yb1/4)2SiO5 monosilicate with low thermal conductivity and excellent resistance to CMAS corrosion

Open Ceramics
The matched CTE with SiC-based ceramics composites, low thermal conductivity and better corrosion resistance against calcium-magnesium-aluminosilicate (CMAS) are the basic requirements for suitable thermal/environmental barrier coating materials for ...

The Growing Behavior of the Ca2Gd8(SiO4)6O2 Dense Reaction Layer in Molten CMAS at High Temperatures

Calcium–magnesium–alumina–silicate (CMAS), as an environmental deposit, deposits on engine components and causes serious damage to traditional thermal barrier coatings (TBCs) at high temperatures.

Study on the Corrosion Behavior of YSZ Thermal Barrier Coatings by CMAS Composition

Yttria-stabilized zirconia (YSZ) thermal barrier coatings (TBCs) were fabricated by atmospheric plasma spraying (APS). Three CMAS powders with different compositions (CMAS-1, CMAS-2, CMAS-3) were selected, and corrosion tests were carried out at 1200 ...

Corrosion of magnesium-yttrium alloys

, 2010
Corrosion of Mg-Y alloys was studied using electrochemical evaluations, immersion tests and direct observations. There were two important effects. In 0.1 M NaCl, the corrosion rate increased with increasing Y content due to increasing amounts of the Y ...
