    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: A braze formulation includes a novel promoter and a metal filler. The promoter includes a blend of potassium tetrafluoroaluminate and potassium tetrafluoroborate. The braze may be used for repairing cracks in a substrate. The braze has a low melt point, removes oxides from within cracks and has improved penetration into cracks for repair.

    Abstract: Disclosed is a method for selectively removing a coating from a substrate. Aluminum is diffused into the coating. The coating is contacted with an aqueous composition including at least one of an acid having the formula H x AF 6 , and precursors to the acid, A being selected from the group consisting of Si, Ge, Ti, Zr, Al, and Ga, and x being 1-6. The coating being removed is often an MCrAl(X) material. The substrate is a metal, usually a superalloy.
