## 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.

## Claims

### Claim at position 1

1-16. (canceled)

### Claim 17

A coated article including a coating supported by a glass substrate, the coating comprising:
a first dielectric layer comprising silicon nitride on the glass substrate;
an IR reflecting layer comprising 63-67 wt. % Ni, 1-2 wt. % Cr, and 25-30 wt. % Mo over and contacting the first dielectric layer;
a layer comprising NbZr over and contacting the IR reflecting layer;
a second dielectric layer comprising silicon nitride over and contacting the layer comprising NbZr; and
an overcoat layer comprising an oxide of zirconium over and contacting the second dielectric layer.

### Claim 18 (depends on 17)

The coated article of claim 17, wherein the coating comprises only one IR reflecting layer, and wherein the coated article is used monolithically.

### Claim 19 (depends on 17)

An insulated glass (IG) unit, comprising:
the coated article of claim 17; and
a second substrate positioned relative to the glass substrate so that the coating is located on surface 1 or on surface 4 of the IG unit.

### Claim 20 (depends on 17)

An insulated glass (IG) unit, comprising:
first and second coated articles according to claim 17,
wherein the first and second coated articles are oriented relative to one another so that coatings on the first and/or second coated articles is/are on an exterior surface of the IG unit.

### Claim 21

A coated article including a coating supported by a glass substrate, the coating comprising:
a first dielectric layer on the glass substrate;
an IR reflecting layer comprising 63-67 wt. % Ni, 1-2 wt. % Cr, and 25-30 wt. % Mo over the first dielectric layer; and
a second dielectric layer on the glass substrate over at least the IR reflecting layer.

### Claim 23 (depends on 21)

The coated article of claim 21, wherein the first and second dielectric layers each comprise silicon nitride.

### Claim 24 (depends on 21)

The coated article of claim 21, further comprising a protective overcoat comprising an oxide of zirconium as an outermost layer of the coating.

### Claim 25 (depends on 21)

The coated article of claim 21, further comprising providing a barrier layer between and contacting the IR reflecting layer and the second dielectric layer.

### Claim 26 (depends on 25)

The coated article of claim 25, wherein the barrier layer comprises NbZr.

### Claim 27 (depends on 21)

The coated article of claim 21, wherein the first and second dielectric layers each comprise silicon nitride, and wherein the coating further comprises a layer comprising NbZr provided between the IR reflecting layer and the second dielectric layer.

### Claim 28 (depends on 21)
