Abstract
Very high strength single phase stainless steel coating has been prepared by magnetron sputtering onto a substrate. The coating has a unique microstructure of nanometer spaced twins that are parallel to each other and to the substrate surface. For cases where the coating and substrate do not bind strongly, the coating can be peeled off to provide foil.
Claims31
A metal foil comprising a surface and a plurality of metal twin planes that are substantially parallel to the surface and parallel to each other and are separated from each other by a twin plane spacing distance of from about 0.5 nm to about 60 nm.
An article of manufacture having a coating, the coating comprising a surface and a plurality of metal twin planes that are substantially parallel to the surface and parallel to each other and wherein adjacent twin planes are separated from each other by a twin plane spacing by a distance of from about 0.5 nm to about 60 nm.
An article of manufacture comprising an object having a coating, the coating comprising a twinned structure having a plurality of metal twin planes that are separated from each other by a twin plane spacing distance of from about 0.5 nm to about 60 nm, wherein the object and the coating have essentially the same chemical composition.
