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 including a coating supported by a glass substrate, the coating comprising:
a first dielectric layer;
an IR reflecting layer over at least the first dielectric layer; and
an oxided contact layer comprising, by % metal, 54-58 wt. % Ni, 20-22.5 wt. % Cr, 12.5-14.5 wt. % Mo, 1-5 wt. % W, and 1-5 wt. % Fe directly contacting the IR reflecting layer.

2. The coated article of claim 1 , wherein the coating is a low-E coating.

3. The coated article of claim 1 , further comprising a layer comprising NbZr located under and directly contacting the oxided contact layer.

4. The coated article of claim 3 , wherein the first dielectric layer comprises silicon nitride.

5. The coated article of claim 1 , wherein the coating comprises a dielectric layer comprising zirconium oxide located over at least the oxided contact layer.

6. The coated article of claim 1 , wherein the contact layer is located over and directly contacting the IR reflecting layer, and wherein the IR reflecting layer comprises silver.

7. The coated article of claim 3 , wherein the oxided contact layer further comprises, by % metal, from 1-5 wt. % Co.
