Synergistic effects of laser-induced dual-layer structure on CMAS corrosion performance of thermal barrier coatings

Materials & Design
Thermal barrier coatings are susceptible to corrosion by molten silicate deposits, commonly referred to as “CMAS” based on their primary constituents (CaO-MgO-Al2O3-SiO2). This has become a growing concern in modern gas turbines.

CMAS-phobic and infiltration-inhibiting protective layer material for thermal barrier coatings

Journal of Advanced Ceramics
Calcium–magnesium–alumina–silicate (CMAS) corrosion has attracted special attention in the thermal barrier coating (TBC) field. At high temperatures, when CMAS melts, it adheres to the coating surface and penetrates the interior, severely destroying the ...
