The present disclosure provides a composite coating and a method for fabricating the composite coating. The composite coating comprises a polymer layer, a metal interlayer and an amorphous metal coating. The polymer layer is formed on a substrate and acts as a diffusion barrier layer, which is thick and dense enough to prevent the corrosive substances from penetrating into the substrate. The metal interlayer is formed between the polymer layer and the amorphous metal coating for improving the adhesion of the amorphous metal coating to the substrate.

A device including a hard shield material; a layer including aluminum or copper; and a silicon layer having a first thickness is disclosed. The device can also include a silicon layer having a second thickness. A method of making the device is also disclosed.

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.
