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.

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 coating system and process capable of providing erosion and corrosion-resistance to a component, particularly a steel compressor blade of an industrial gas turbine. The coating system includes a metallic sacrificial undercoat on a surface of the component substrate, and a ceramic topcoat deposited by thermal spray on the undercoat. The undercoat contains a metal or metal alloy that is more active in the galvanic series than iron, and electrically contacts the surface of the substrate. The ceramic topcoat consists essentially of a ceramic material chosen from the group consisting of mixtures of alumina and titania, mixtures of chromia and silica, mixtures of chromia and titania, mixtures of chromia, silica, and titania, and mixtures of zirconia, titania, and yttria.
