ABSTRACT:
A process is provided for cleaning a surface of an internal cavity of a gas turbine component having sulfidation or sulfur bearing deposits comprising: inserting into the internal cavity a fluoride salt; and heating the fluoride salt and the component in an inert atmosphere for a time and at a temperature to clean the sulfidation or sulfur bearing deposits on the surface. In a preferred embodiment the cleaned internal surface is then coated with a metallic coating.
