  • Methods and apparatus for coating gas turbine components
    Publication number: 20070141272
    Abstract: Methods and apparatus for forming a metal coating on a surface of a workpiece are provided. The method includes positioning the workpiece in a microwavable chamber, positioning a coating material in the microwavable chamber, and heating at least the workpiece and the coating material using microwave range electromagnetic energy such that a diffusion coating of the coating material is formed on the surface of the workpiece.

  • Method for removing aluminide coating from metal substrate and turbine engine part so treated
    Publication number: 20050244274
    Abstract: A method for selectively removing an aluminide coating from at least one surface of a metal-based substrate by: (a) contacting the surface of the substrate with at least one stripping composition comprising nitric acid at a temperature less than about 20° C. to degrade the coating without damaging the substrate; and (b) removing the degraded coating without damaging the substrate. Also disclosed is a method for replacing a worn or damaged aluminide coating on at least one surface of a metal-based substrate by selectively removing the coating using the above steps, and then applying a new aluminide coating to the surface of the substrate. Turbine engine parts, such as high-pressure turbine blades, treated using the above methods are also disclosed.
