    Abstract: Disclosed herein is a method for aluminiding an internal passage of a metal substrate comprising injecting a slurry composition that comprises a powder comprising aluminum, a binder selected from the group consisting of colloidal silica, an organic resin, and a combination thereof, into the internal passage; applying compressed air to the internal passage to facilitate distribution of the slurry composition throughout the internal passage; and, heat treating the slurry composition under conditions sufficient to remove volatile components from the composition, and to cause diffusion of aluminum into a surface of the internal passage.

    Abstract: The present invention provides a method for sealing pinholes in an electroless metal coating, said method comprising: (a) coating a substrate with an electroless metal coating layer to provide a coated article comprising an electroless metal coating in contact with the surface of the substrate, said electroless metal coating being characterized by the presence of pinhole imperfections which allow fluid communication between the substrate and the environment; (b) applying a layer of a curable epoxy sealant over the electroless metal coating layer and filling the pinhole imperfections; (c) curing the curable epoxy sealant to provide a cured epoxy overcoating layer; and (d) removing a substantial portion of the cured epoxy overcoating layer to provide an article comprising an electroless metal coating which is substantially free of pinhole imperfections allowing fluid communication between the substrate and the environment.

    Abstract: Methods of fabricating coated components (100) using multiple types of fillers are provided. One method comprises forming one or more grooves (132) in an outer surface (112) of a substrate (110). Each groove has a base (134) and extends at least partially along the outer surface. A sacrificial filler (32) is deposited within the groove(s), a second filler (33) is deposited over the sacrificial filler (32), and a coating (150) is disposed over at least a portion of the outer surface and over the second filler. The method further includes removing the sacrificial filler and at least partially removing the second filler from the groove(s), to define one or more channels (130) for cooling the component.

    Abstract: An electrode (110) for rejuvenating a cooling passage (101) within an airfoil, the electrode including a tip (130), an end (140), a conductive core (116) extending between the tip and the end, and an insulating coating (118) disposed on the conductive core. The insulating coating exposes a number of conductive strips (150) of the conductive core extending between the tip and the end. The insulating coating forms a number of insulating portions (160) and further exposes a number of spacer portions (133) of the conductive core longitudinally positioned between the insulating portions. The insulating portions substantially span a distance between the tip and the end and are positioned between the conductive strips.
