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 NixCryMoz-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 from the glass substrate outwardly comprising:
a first dielectric layer on the glass substrate;
an oxided 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;
a second dielectric layer on the glass substrate and over at least the first dielectric layer and the oxided 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;
wherein the oxided 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 is located between and directly contacting the first and second dielectric layers;
a first IR reflecting layer comprising silver over at least the first and second dielectric layers;
a third dielectric layer located over at least the first 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 , wherein the first and second dielectric layers comprise silicon nitride.

4. The coated article of claim 1 , wherein the coating further comprises a dielectric layer comprising zirconium oxide located over at least the third dielectric layer.

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

6. The coated article of claim 1 , wherein the first dielectric layer directly contacts the glass substrate.

7. A coated article including a coating supported by a glass substrate, the coating from the glass substrate outwardly comprising:
a first dielectric layer comprising silicon nitride on the glass substrate;
a 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;
a second dielectric layer comprising silicon nitride on the glass substrate and over at least the first dielectric layer comprising silicon nitride and the 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;
wherein the 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 is located between and directly contacting the first and second dielectric layers comprising silicon nitride;
a first IR reflecting layer comprising silver over at least the first and second dielectric layers comprising silicon nitride;
a third dielectric layer located over at least the first IR reflecting layer.

8. The coated article of claim 7 , wherein the coating is a low-E coating.

9. The coated article of claim 7 , wherein the coating further comprising a second IR reflecting layer comprising silver located on the substrate over at least the third dielectric layer.

10. The coated article of claim 7 , wherein the coating further comprises a dielectric layer comprising zirconium oxide located over at least the third dielectric layer.

11. The coated article of claim 7 , wherein the 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, further comprises from 1-5% Co.

12. The coated article of claim 7 , wherein the first dielectric layer directly contacts the glass substrate.
