    摘要: 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.

    摘要: An article having a thermal barrier coating includes a superalloy substrate having a columnar grained ceramic coat formed thereon. The ceramic coat includes a nanolaminate region comprising repeating layers of ceramic material with each layer being less than 500 nm in thickness, with dispersions of metal oxide doping material situated between each of the layers. The ceramic coat further includes a non-doped region having a thickness greater than 500 nm adjacent to the nanolaminate region, the non-doped region including one layer or a plurality of adjacent layers of ceramic material without dispersions of metal oxide doping material situated between each of the layers. In one embodiment, and by way of example only, a bond coat is formed between the substrate and the columnar grained ceramic coat. According to another embodiment, the superalloy substrate forms an adherent alumina scale, and no bond coat is necessary.

    摘要: The present invention thus provides an improved method for coating turbine engine components. The method utilizes a cold high velocity gas spray technique to coat turbine blades, compressor blades, impellers, blisks, and other turbine engine components. These methods can be used to coat a variety of surfaces thereon, thus improving the overall durability, reliability and performance of the turbine engine itself. The method includes the deposition of powders of alloys of nickel and aluminum wherein the powders are formed so as to have an amorphous microstructure. Layers of the alloys may be deposited and built up by cold high velocity gas spraying. The coated items displayed improved characteristics such as hardness, strength, and corrosion resistance.
