摘要： A restored or regenerated article including a residual substrate comprised of a first material and a restorative or regenerative layer of second material overlying at least a portion of the residual substrate. The second material is substantially similar in composition to the first material to promote an integral bond therebetween. The second material comprises the deposit of a suitable deposition process, i.e., vapor phase deposition, cathodic arc deposition, or sputtering. The restored/regenerated article includes an environmental coating at least partly diffused into the restorative or regenerative layer. The environmental coating comprises a deposit from a deposition process selected from vapor phase deposition, cathodic arc deposition, and combinations thereof. Heat treatments of about 2 hours or longer at temperatures between about 1500 ° F. to about 2300° F. (about 816° C. to about 1260° C.) to enhance the bond between the residual substrate and the restorative/regenerative layer. Surface characteristics of the restored/regenerated component may be enhanced by a suitable surface treatment such as grit blast polishing.

摘要： A protected article includes a substrate having a substrate surface and made of a substrate nickel-base superalloy that is susceptible to the formation of a secondary reaction zone, as when contacted by an aluminum-containing layer having more than about 20 percent by weight aluminum. A protective layer contacts the substrate surface. The protective layer is of a different composition than the substrate and is made of a protective-layer nickel-base superalloy having from about 7 to about 12 percent by weight aluminum. Preferably, a thermal barrier coating system including a ceramic layer overlies and contacts the protective layer.

摘要： A method for welding iron-based or nickel-based superalloy assemblies into a unitary article. First, the assemblies are heated in an air atmosphere, at a rate suitable to minimize geometric distortion, to a temperature in the range of about 1400F (760C) to about 2000° F. (1090° C.) to form an oxide layer on the surface of the assemblies and optionally as a pre-weld solution heat treat. The temperature of the assemblies are then held in a range of about 1400F (760C) to about 2000° F. (1090° C.) for a time sufficient to form an oxide layer of sufficient thickness on the surface of the assemblies and optionally to solution the assemblies. The assemblies are then cooled to ambient temperature at a rate sufficient to avoid precipitation of unwanted metal phases at a rate sufficient to maintain dimensional stability. The oxide layer is then removed from at least the faying surfaces of the assemblies, but not from the face side of the assemblies. The faying surfaces of the assemblies are then cleaned. The assemblies are then welded using a GTA welding procedure to form a unitary article. The article is then resolutioned at an appropriate temperature for an appropriate period of time, both of which are dependent on the type of superalloy(s) that is present in the welded article and the desired properties. The article is then optionally age heat treated at an appropriate temperature for an appropriate period of time, both of which are dependent on the type of superalloy(s) that is present in the welded unitary article.
