Barrier layers comprising ni-inclusive alloys and/or other metallic alloys, double barrier layers, coated articles including double barrier layers, and methods of making the same

Abstract

Certain example embodiments relate to Ni-inclusive ternary alloy being provided as a barrier layer for protecting an IR reflecting layer comprising silver or the like. The provision of a barrier layer comprising nickel, chromium, and/or molybdenum and/or oxides thereof may improve corrosion resistance, as well as chemical and mechanical durability. In certain examples, more than one barrier layer may be used on at least one side of the layer comprising silver. In still further examples, a Ni x Cr y Mo z -based layer may be used as the functional layer, rather than or in addition to as a barrier layer, in a coating.
