ABSTRACT:
An abrasive, wear resistant layer is applied to the tip surface of a superalloy gas turbine blade by high temperature sintering operation which produces a high strength bond between the layer and the blade, minimizes gamma prime phase growth, and prevents recrystallization in the blade. Important features of the invention include the use of an inductively heated graphite susceptor to heat the blade, and a refractory metal shield which surrounds the airfoil and root portions of the blade while leaving the tip portion exposed to the heat source.
