Abstract
A vanadium resistant coating system resistant to high temperature vanadium attack. The system comprises a high temperature superalloy substrate (10). A bond coat (20) overlies the superalloy substrate (10). The bond coat (20) may be applied in multiple layers. A ceramic coating (40) overlies the bond coat. The ceramic coating (40) further comprises a zirconium oxide stabilized by at least one cation selected from the group consisting of Yb<3+>, Lu<3+>, Sc<3+>and Ce<4+>, in the amounts of about 5-10 weight percent. An overcoat may overlie the ceramic coating. The overcoat may be a sacrificial layer of YSZ infiltrated with cations having an atomic radius larger than Y<3+>. Alternatively, the overcoat may comprise zirconium oxide stabilized by Ce<4+>.
