Abstract
Methods for producing a high temperature oxidation resistant coating on a superalloy component and the coated superalloy component produced thereby are provided. Aluminum or an aluminum alloy is applied to at least one surface of the superalloy component by electroplating in an ionic liquid aluminum plating bath to form a plated component. The plated component is heat treated at a first temperature of about 600° C. to about 650° C. and then further heat treated at a second temperature of about 700° C. to about 1050° C. for about 0.50 hours to about two hours or at a second temperature of about 750° C. to about 900° C. for about 12 to about 20 hours.
