    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: The article comprising an antifouling surface is provided. The surface comprises a material having a nominal liquid wettability sufficient to generate, with reference to an oil, a nominal contact angle of at least about 30 degrees; and a texture comprising a plurality of features disposed on the surface. The features have a size, shape, and orientation selected such that the surface has an effective wettability sufficient to generate, with reference to an oil, an effective contact angle greater than the nominal contact angle. The features comprise a height dimension (h), a width dimension (a), a spacing dimension (b) such that, ratio b/a is less than about 4, and ratio h/a is less than about 10. In one embodiment, a turbine component comprising an antifouling surface is provided.
