## Abstract

Certain example embodiments relate to a coated article including at least one infrared (IR) reflecting layer of a material such as silver or the like in a low-E coating, and methods of making the same. In certain cases, at least one layer of the coating is of or includes nickel and/or titanium (e.g., NixTiyOz). The provision of a layer including nickel titanium and/or an oxide thereof may permit a layer to be used that has good adhesion to the IR reflecting layer, and reduced absorption of visible light (resulting in a coated article with a higher visible transmission). When a layer including nickel titanium oxide is provided directly over and/or under the IR reflecting layer (e.g., as a barrier layer), this may result in improved chemical and mechanical durability. Thus, visible transmission may be improved if desired, without compromising durability; or, durability may simply be increased.

## Claims

### Claim at position 1

1-22. (canceled)

### Claim 23

A coated article comprising:
a glass substrate;
a first dielectric layer supported by the glass substrate;
a lower contact layer, wherein the first dielectric layer is located between at least the glass substrate and the lower contact layer;
an infrared (IR) reflecting layer comprising silver located on an directly contacting the lower contact layer;
an upper contact layer located on and directly contacting the IR reflecting layer, wherein the upper contact layer comprises an oxide of Ni and Ti,
wherein the two largest metals by content in the upper contact layer are Ni and Ti;
wherein the upper contact layer comprises more Ti than Ni, and
wherein metal content of the upper contact layer comprises from about 70-90% Ti (weight percentage).

### Claim 24 (depends on 23)

An insulated glass (IG) unit, comprising:
the coated article of claim 23; and
a second glass substrate being substantially parallel to and spaced apart from the coated article.

### Claim 25 (depends on 23)

The coated article of claim 23, wherein the upper contact layer comprises Ni:Ti in a ratio of about 20:80 (by weight).

### Claim 26 (depends on 23)

The coated article of claim 23, wherein the upper contact layer has a thickness of from about 10 to 45 Angstroms.

### Claim 27 (depends on 23)

The coated article of claim 23, wherein the coated article contains only one IR reflecting layer comprising silver.

### Claim 29 (depends on 23)

The coated article of claim 23, further comprising a layer comprising an oxide and/or nitride of silicon on the glass substrate over at least the upper contact layer, wherein the layer comprising the oxide and/or nitride of silicon is an outermost layer of a coating including the recited layers.

### Claim 30 (depends on 23)

The coated article of claim 23, further comprising another IR reflecting layer comprising silver.

### Claim 31 (depends on 23)

The coated article of claim 23, wherein the lower contact layer comprises an oxide of Ni and Ti.
