    Abstract: A mid-span shroud assembly for a turbine blade airfoil includes a pressure side shroud body which is associated with a pressure side wall of the airfoil and a suction side shroud body which is associated with a suction side wall of the airfoil. At least one of the pressure side shroud body and the suction side shroud body defines a coupling spar which is formed to extend at least partially through a bore hole defined within the airfoil of the turbine blade.

    Abstract: A brazing method is disclosed. The brazing method includes providing a substrate, providing at least one groove in the substrate, providing a support member, positioning the support member over the at least one groove in the substrate, providing a braze material, applying the braze material over the support member to form an assembly, and heating the assembly to braze the braze material to the substrate. Another brazing method includes providing a preform, providing a wire mesh, pressing the wire mesh into the preform, heating the preform to form a braze material including the wire mesh, providing a substrate, providing at least one groove in the substrate, applying the braze material over the at least one groove in the substrate, then brazing the braze material to the substrate.

    Abstract: A method for fabricating an airfoil includes forming a diffuser section in an exterior surface of the airfoil. The diffuser section is defined by at least an outer surface and an inner surface that converge at a stop surface. The method also includes positioning a drilling element of a drilling device on the stop surface. The method further includes orienting the drilling element at a first angle relative to the exterior surface. The method also includes forming, using the drilling element, a cooling channel extending through the airfoil from the stop surface to an interior surface, thereby forming the cooling channel at substantially the first angle.
