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
View Patent ↗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.
1. A coated article including a coating supported by a glass substrate, the coating comprising:
a first dielectric layer;
an IR reflecting layer comprising silver over at least the first dielectric layer; and
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 over at least 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 , wherein the first dielectric layer comprises silicon nitride.
4. The coated article of claim 1 , wherein the coating comprises a dielectric layer comprising zirconium oxide located over at least the oxided 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. The coated article of claim 1 , further comprising a dielectric layer comprising silicon nitride located over the oxided layer.
8. The coated article of claim 7 , wherein the dielectric layer comprising silicon nitride is located directly on and contacting the oxided layer.
