Patent ID: 8778164

Claim:
A method for producing a high temperature oxidation resistant coating on a superalloy component, the method comprising the steps of: applying aluminum or an aluminum alloy to at least one surface of the superalloy component by electroplating at electroplating conditions in an ionic liquid aluminum plating bath forming a plated component, the ionic liquid aluminum plating bath comprising an ionic liquid having a melting point less than 100° C. and an aluminum salt; and heat treating the plated component in a first heating step at a first temperature of 600 to 650° C. for about 15 to about 45 minutes and then further heat treating the plated component in a second heating step at a second temperature of 700° C. to 1050° C. for about 0.50 hours to about two hours or 750° C. to 900° C. for about 12 to about 20 hours.
