Abstract
A superalloy workpiece includes a superalloy substrate and an interface layer (IF-1) of essentially the same superalloy composition directly on a surface of the superalloy substrate. A transition layer (TL) of essentially the same superalloy and superalloy oxides or a different metal composition and different metal oxides is on the interface layer (IF-1). The oxygen content of the transition layer increases from the interface layer (IF-1) towards a barrier layer (IF-2) of super alloy oxides or of different metal oxides.
