Hot corrosion behavior of nanostructured Gd2O3 doped YSZ thermal barrier coating in presence of Na2SO4 + V2O5 molten salts

Nickel-based superalloy DZ125 was first sprayed with a NiCrAlY bond coat and followed with a nanostructured 2 mol% Gd2O3−4.5 mol% Y2O3-ZrO2 (2GdYSZ) topcoat using air plasma spraying (APS). Hot corrosion behavior of the as-sprayed thermal barrier coatings (TBCs) were investigated in the presence of...
