Abstract
A coated article, and a corresponding method of making the same are provided. The coated article includes a coating supported by a substrate, the coating including a thin metal or metal nitride contact layer (e.g., NiCr, Ni, Cr, CrNx or NiCrNx) located directly between and contacting an infrared (IR) reflecting layer (e.g., Ag) and an oxide barrier layer (e.g., NiCrOx).
Claims28
A method of making a coated article, the method comprising:
- providing a glass substrate;
- depositing a first dielectric layer so as to be supported by the substrate;
- depositing an Ag layer on the substrate over the first dielectric layer;
- depositing, using a first sputtering target, a metal or metal nitride contact layer on the substrate directly over and in contact with the Ag layer;
- depositing, using a second sputtering target different than the first sputtering target, a layer comprising an oxide of NiCr on the substrate directly over and in contact with the metal or metal nitride contact layer;
- and
- depositing another dielectric layer on the substrate over the layer comprising the oxide of NiCr.

A method of making a coated article comprising:
- providing a glass substrate;
- sputtering a first metal oxide inclusive layer on the glass substrate;
- sputtering a layer comprising silver on the substrate over at least the first metal oxide inclusive layer;
- using a first target, sputtering a layer comprising Ni on the substrate directly over and contacting the layer comprising silver;
- using a second target, sputtering a layer comprising an oxide of NiCr over and contacting the layer comprising Ni, so that the layer comprising Ni and the layer comprising an oxide of NiCr are sputtered using different targets;
- and
- sputtering a second dielectric layer on the substrate over at least the layer comprising an oxide of NiCr.
