Combined coat, heat treat, quench method for gas turbine engine components

摘要

A method for imparting an aluminide coating to an alloy gas turbine engine component (32), heat treating the component (32), and quenching the component (32). The component (32) 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 (32), 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 (32) in the coating furnace to cool the component (32) 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. <IMAGE>
