Abstract
A method for generating an internal pack coating having different, controlled thicknesses includes partially filling a root opening of a turbine blade having a cavity therein with a first powder and a second powder having different formulations so that the first powder contacts a first predefined portion of the surface of the cavity and the second powder contacts a second predefined portion of the surface of the cavity. The method further includes heating the object with the first powder and the second powder therein to thereby produce a coating of the internal cavity having different coating thicknesses over the first portion of the surface of the cavity and the second portion of the surface of the cavity.
