Zusammenfassung:	A method of sealing a generator stator bar and a stator bar end fitting receiving the end including the steps of: brazing the fitting to the end of the stator bar with a braze material; applying a metallic barrier coating material to the end of the stator bar in the fitting; heating the fitting at a temperature at least as hot as a liquidus temperature of the metallic coating material and cooler than a solidus temperature of the braze material; coating the end of the stator bar in the fitting with liquid metallic barrier coating material, and solidifying the liquefied metallic coating material to form a metallic barrier coating on the end of the stator bar in the fitting.
