Beschreibung
Zusammenfassung:	A restored or regenerated article, particularly a component for use in a gas turbine engine, restored or regenerated by a method including: providing a worn component (80) comprised of a first material, evaluating a wall thickness of the residual substrate (84), and depositing a layer of a second material overlying at least a portion of the residual substrate (86A, 86B). The second material is substantially similar in composition to the first material. In a coating step (92), an environmental coating is deposited onto the component. The method may include a heat treatment step (88) at temperatures between about 816 °C to about 1260 °C for between about 2 to about 24 hours. The restored or regenerated article may be returned to service (98).
