  • MICROWAVE ASSISTED CHEMICAL STRIPPING OF COATINGS
    Publication number: 20090301515
    Abstract: A method for chemically stripping a metallic coating from a substrate is described. The coating is treated in the presence of microwave energy with a solution containing at least one acid known to dissolve the coating. The application of microwave energy accelerates the dissolution and allows for the use of diluted solutions. Coatings of interest include diffusion aluminides on superalloy substrates.
