1. A method of applying a wear-resistant hardface alloy to a portion of a turbine blade, comprising:

  • placing a thin foil of a brazing alloy over a mating surface of said portion of said turbine blade;

    positioning a hardface alloy of a greater-than-desired thickness over said foil, thereby sandwiching the foil between said portion of said turbine blade and said hardface alloy;

    heating said portion of said turbine blade, foil, and hardface alloy for a period sufficient to melt said foil and cause bonding of said hardface alloy to said portion of said turbine blade; and

    thereafter machining said hardface alloy so as to reduce said greater-than-desired thickness to a desired lesser thickness.
