Abstract
Methods for refurbishing aerospace components by removing corrosion and depositing protective coatings are provided herein. In one or more embodiments, a method of refurbishing an aerospace component includes exposing the aerospace component containing corrosion to an aqueous cleaning solution. The aerospace component contains a nickel superalloy, an aluminide layer disposed on the nickel superalloy, and an aluminum oxide layer disposed on the aluminide layer. The method includes removing the corrosion from a portion of the aluminum oxide layer with the aqueous cleaning solution to reveal the aluminum oxide layer, then exposing the aluminum oxide layer to a post-rinse, and forming a protective coating on the aluminum oxide layer.
