Plane protection: Alumina and titania improve the corrosion resistance of thermal barrier coatings to molten glass

By Lisa McDonald / August 18, 2023

Thermal barrier coatings protect engine components from extreme heat, but they can be damaged by the dust that gets sucked in and turned into molten glass. Previous studies found yttria-stabilized zirconia coatings doped with alumina and titania demonstrated improved corrosion resistance against this molten glass. Now, researchers in Turkey explored whether these additives could improve the resistance of ceria-stabilized coatings as well.
