A system for restoring or regenerating an article, such as turbine blade or vane for a gas turbine engine, includes a first cathode and a second cathode operably disposed in a deposition chamber. The first cathode includes a first deposition material substantially similar in composition to the material of a residual substrate. The second cathode includes a second deposition material able to form an environmental coating on a restored/regenerated component. The first and second cathodes may be sequentially operated without interrupting the vacuum conditions in the deposition chamber. A method for restoring or regenerating an article includes utilizing the first cathode to deposit a layer of first deposition material onto the residual substrate and subsequently applying the environmental coating utilizing a common deposition chamber, and without interrupting the vacuum conditions between depositions.
