Construction of a molten CMAS-resistant bilayer-structured apatite layer used for thermal barrier coatings

Journal of Advanced Ceramics
Molten calcium–magnesium–alumina–silicate (CMAS) is easy to wet and penetrates into thermal barrier coatings (TBCs), causing coating corrosion and premature failure.

Erosion-corrosion mitigation using chemicals [PDF]

, 2007
The presence of entrained sand in oil and gas production is becoming increasingly prevalent as wells age and this is leading to erosion-corrosion in C02-saturated conditions becoming a major mechanism of material attack. Its understanding, prediction and

Dense core–shell eutectic Zr–Ta–O as a sacrificial layer of YSZ topcoat for enhanced CMAS resistance via dynamic sealing and self-removal

Journal of Advanced Ceramics
Thermal barrier coatings (TBCs) are critical in protecting hot-section components. A double-layered TBC system comprising a eutectic Zr–Ta–O (ZTO) core–shell structured top layer and a yttria-stabilized zirconia (YSZ) underlayer was fabricated via ...

Corrosion resistance of galvanized steel in concrete: effect of wet-dry cycles in chloride solution after carbonation process

, 2013
The effect of chloride ions on corrosion resistance of galvanized steel in carbonated concrete was investigated. Galvanized steel sheets were embedded in cubic concrete specimens manufactured with a 52.5 R Portland cement; after curing in atmosphere for ...

A Comprehensive Analysis of CMAS Characterization, Corrosion Scenarios, and Protective Measures

Science and Technology of Engineering, Chemistry and Environmental Protection
Aero engines face significant corrosion risks from environmental sediments like volcanic ash, industrial smoke, automobile exhaust, and PM2.5 during high-altitude flights. These deposits, composed of CaO-MgO-Al2O3-SiO2 (CMAS), have a melting point of 1230°C, substantially lower than the operating temperature of aero engines.
