Abstract
A coated substrate having a coating and a method of forming the same is disclosed, wherein the coating includes a plurality of discrete layers. The coating includes three reflective layers, an alloy layer disposed between two of the reflective layers, and two oxide layers and has a total thickness of 4000 Å or less.

A coated substrate, comprising:
- a light transmissive substrate having one or more major surfaces;
- and
- a coating disposed on at least a portion of one major surface of the substrate, the coating comprising a plurality of discrete layers, including:
- a first reflective layer;
- a second reflective layer disposed above the first reflective layer;
- a third reflective layer disposed above the second reflective layer;
- a first oxide layer disposed between the first and second reflective layers;
- a second oxide layer disposed between the second and third reflective layers;
- a third oxide layer disposed between the substrate and the first reflective layer;
- and
- an alloy layer disposed between the first and second reflective layers and contiguous to the second reflective layer, wherein the alloy layer comprises at least about 58 weight % Ni, about 20 to about 23 weight % Cr, about 8 to about 10 weight % Mo, about 3.15 to about 4.15 weight % Nb+Ta, and less than about 5 weight % Fe;
- wherein the coating has a thickness of about 1000 Å to 4000 Å.

An insulated glass unit, comprising:
- at least two light transmissive substrates each having one or more major surfaces;
- a substrate mounting unit containing the at least two substrates, wherein the substrate mounting unit holds the at least two substrates in a substantially parallel configuration, and the substrate mounting unit and at least two substrates collectively form an enclosed space;
- a coating disposed on at least a portion of at least one of the major surfaces, the coating comprising a plurality of discrete layers, including:
- a first reflective layer;
- a second reflective layer disposed above first reflective layer;
- a third reflective layer disposed above second reflective layer;
- a first oxide layer disposed between first and second reflective layers;
- a second oxide layer disposed between second and third reflective layers;
- a third oxide layer disposed between the substrate and the first reflective layer;
- and
- an alloy layer disposed between first and second reflective layers and contiguous to the second reflective layer, wherein the alloy layer comprises at least about 58 weight % Ni, about 20 to about 23 weight % Cr, about 8 to about 10 weight % Mo, about 3.15 to about 4.15 weight % Nb+Ta, and less than about 5 weight % Fe;
- wherein the coating has a thickness of about 1000 Å to 4000 Å.
