Abstract: Exemplary embodiments of the invention provide barrier coated substrates and methods of coating a substrate with a barrier coating derived from sol gels. An example includes a barrier coated aerospace component that is subject to hot salt corrosion during use. The barrier coating is derived from oxidation of a coating composition that includes at least one sol gel. The barrier coating resists hot salt corrosion for an incubation period of such duration that an uncoated superalloy substrate under the same conditions would suffer corrosion to a depth of about 2.0 mils. Methods of applying the barrier coating include the steps of selecting a first liquid sol gel and wetting surfaces of the superalloy substrate with the selected first liquid sol gel. The wetted surfaces of the superalloy substrate are subjected to heat treatment. The heat treatment includes sintering of sol gel to oxide to produce a barrier coating.

Abstract: A method is provided for coating a hollow, internally cooled blade (1) of a gas turbine, in which method an outer coating (5) comprising an MCrAlY-based bonding layer (6) and a ceramic thermal barrier layer (9) of zirconium oxide is applied to the base material (3) of the blade (1) on the outer side of the blade (1) and an inner coating (4) comprising a Cr diffusion layer (7) is applied to the base material (3) of the blade (1) on the inner side of the blade (1). The MCrAlY-based bonding layer (6) is thereby applied to the finished blade (1). At the same time, along with the inner coating (4), the Cr diffusion layer (7) is also applied to the MCrAlY-based bonding layer (6) of the outer coating (5) by chemical vapor deposition. Subsequently, an Al diffusion layer (8) and an outer brittle Al build-up layer are applied by chemical vapor deposition to the bonding layer (6) coated with the Cr diffusion layer (7). After that, the outer brittle Al build-up layer is removed by an abrasive treatment and the ceramic thermal barrier layer (9) is applied to the Al diffusion layer (8).

Abstract: A thermally protective coating (21), such as may be used over a nickel-based superalloy substrate (24). The protective coating (21) includes a CoNiCrAlY or a NiCoCrAlY material and addition of given amounts of one or more secondary elements. The secondary element(s) facilitate and/or join in one or more precipitation mechanisms (γ′, B2) that retain an aluminum reservoir in the protective coating (21), reducing aluminum diffusion into the substrate (24). This aluminum reservoir maintains a protective alumina scale (38) on the coating (21), thus improving coating life and allowing higher operating temperatures.
