Failure and Protection of Thermal Barrier Coating under CMAS Attack
Journal of Aeronautical Materials, 2018 Along with the increase of operating temperature of aero-engine, thermal barrier coatings （TBCs） used in the engine are highly susceptible to the attack of glassy silicate deposits, the chemical composition of which is mostly CaO-MgO-Al2O3-SiO2 （CMAS ...
