Filed:

Feb 9, 2007

Appl. No.:

11/704447

Inventors:

Derek Raybould - Denville NJ, US
Thomas E. Strangman - Prescott AZ, US
Christian DelaCruz - Parsippany NJ, US

International Classification:

B05D 3/02

US Classification:

4273977

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.

US Classification:

427585, 4272481, 427380, 4273977, 427402, 428446

Abstract:

Protective coating systems for gas turbine engine applications and methods for fabricating such protective coating systems are provided. An exemplary method of fabricating a protective coating system on a substrate comprises forming a bond coating on the substrate, forming a silicate layer on the bond coating, forming a thermal barrier coating overlying the silicate layer, and heating the thermal barrier coating.

International Classification:

B32B 9/00
B05D 3/02

US Classification:

428446, 4273977

Abstract:

Components and methods of forming a protective coating system on the components are provided. In an embodiment, and by way of example only, the component includes a ceramic substrate and a braze layer disposed over the ceramic substrate. The braze layer includes a silicon matrix having a first constituent and a second constituent that is different than the first constituent. The first constituent forms a first intermetallic with a portion of the silicon matrix and the second constituent forms a second intermetallic with another portion of the silicon matrix, wherein the braze layer is formulated to provide a barrier to oxygen diffusion therethrough.

Abstract:

Protective coating systems for gas turbine engine applications and methods for fabricating such protective coating systems are provided. An exemplary protective coating system comprises an aluminide-comprising bond coating disposed on a substrate, a thermal barrier coating overlying the aluminide-comprising bond coating, and a silicate layer interposed between the thermal barrier coating and the aluminide-comprising bond coating.

International Classification:

C01B 33/12

US Classification:

423335, 427 77, 423625, 423608

Abstract:

A coating for spark plugs and engine parts is resistant to fouling. The coating may be applied to the spark plug or engine part by dipping the part in a sol gel solution, ensuring it wets the part, and extracting it at a slow, controlled rate. As the part is allowed to dry, the sol gel reacts with moisture in the air to form a thin oxide film. Unlike conventional sol gel applications, which apply the oxide directly to the part, the present invention may form an oxide coating, in situ, while drying in place on the part.
