Abstract
A method for imparting an aluminide coating to an alloy gas turbine engine component, heat treating the component, and quenching the component. The component is exposed to a source of aluminum at an elevated temperature in a coating furnace to deposit an aluminum-based oxidation barrier on the component, heated in the coating furnace to a temperature of at least the solution temperature of the alloy, and quenched by flowing a chilled inert gas around the component in the coating furnace to cool the component from the temperature of at least the solution temperature of the alloy to a temperature at which a gamma′ phase of the alloy is set in the alloy in less than about 10 minutes.
