    摘要： A vanadium resistant coating system resistant to high temperature vanadium attack. The system comprises a high temperature superalloy substrate. A bond coat overlies the superalloy substrate. The bond coat may be applied in multiple layers. A ceramic coating overlies the bond coat. The ceramic coating further comprises a zirconium oxide stabilized by at least one cation selected from the group consisting of Yb3+, Lu3+, Sc3+ and Ce4+, 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 Y3+. Alternatively, the overcoat may comprise zirconium oxide stabilized by Ce4+.

    摘要： A compressor blade for use in a compressor section of a gas turbine engine, comprising: a martensitic stainless steel compressor blade and an abrasive coating having an anodic component. The compressor blade has a blade portion, a dovetail portion and a platform portion intermediate the blade portion and the dovetail portion, the blade portion terminating in a tip opposite the dovetail portion. A cobalt-based coating overlies at least the blade portion of the compressor blade. The cobalt-based coating comprises a cobalt based material that includes precipitates of tungsten carbide that provide erosion resistance and particles of a sacrificial metal-based material distributed through the cobalt-based coating that provide galvanic corrosion resistance to the system.
