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.

First claim

What is claimed is:

1. A coated article comprising a low-E coating, the low-E coating supported by a glass substrate and comprising:
a dielectric layer;
an IR reflecting layer comprising silver over at least the first dielectric layer;
a first oxided barrier layer comprising, by % metal, 60-65 wt. % Ni, 12-17 wt. % Cr, 20-25 wt. % Mo, and 1-3 wt. % Fe over and directly contacting the IR reflecting layer;
a second barrier layer comprising Nb and Zr, the second barrier layer c…
