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 coating supported by a glass substrate, with the coating comprising:
a dielectric layer;
an IR reflecting layer comprising silver on the glass substrate and over at least the dielectric layer;
an oxided barrier layer comprising, by % metal, 54-58 wt. % Ni, 20-22.5 wt. % Cr, 1-5 wt. % Co, 1-5 wt. % W, and 12.5-14.5 wt. % Mo over and directly contacting the IR reflecting layer;
another barrier layer comprising Nb and Zr over the oxided barrier layer comprising, by % metal, 54-58 wt. % Ni, 20-22.5 wt. % Cr, 1-5 wt. % Co, 1-5 wt. % W, and 12.5-14.5 wt. % Mo; and
another dielectric layer on the glass substrate located over at least the another barrier layer.

2. The coated article of claim 1 , wherein the article comprises only one IR reflecting layer.

3. The coated article of claim 1 , wherein the barrier layers are oxided.

4. The coated article of claim 1 , further comprising a layer comprising an oxide of zirconium over at least said another dielectric layer.

5. An insulated glass (IG) unit, comprising: the coated article of claim 1 ; and a second substrate substantially parallel and spaced apart from the coated article; and a spacer system.

6. A coated article comprising a coating supported by a glass substrate, with the coating comprising:
a dielectric layer;
an IR reflecting layer comprising silver on the glass substrate and over at least the dielectric layer;
an oxided layer comprising, by % metal, 54-58 wt. % Ni, 20-22.5 wt. % Cr, 1-5 wt. % Co, 1-5 wt. % W, and 12.5-14.5 wt. % Mo over and directly contacting the IR reflecting layer; and
another dielectric layer on the glass substrate located over at least the IR reflecting layer and the oxided layer comprising, by % metal, 54-58 wt. % Ni, 20-22.5 wt. % Cr, 1-5 wt. % Co, 1-5 wt. % W, and 12.5-14.5 wt. % Mo.
