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

A method of making a coated article including a coating supported by a glass substrate, the method comprising:

• disposing a dielectric layer on the substrate;
• disposing a first sub-barrier layer comprising one or more of Nb, Ti, Cr, and Zr over the dielectric layer;
• disposing a first barrier layer comprising Ni, Cr, Ti, and/or Mo over the first sub-barrier layer;
• disposing an IR reflecting layer comprising silver over and contacting the first barrier layer comprising Ni, Cr, Ti, and/or Mo;
• disposing a second oxided barrier layer comprising 54-58 wt. % Ni, 20-22.5 wt. % Cr, and 12.5-14.5 wt. % Mo over and contacting the IR reflecting layer;
• and
• disposing a second sub-barrier layer comprising one or more of Nb, Ti, Cr, and Zr over the second oxided barrier layer.
