Abstract
In certain example embodiments, a coated article includes a Zn-doped zirconium based layer before heat treatment (HT). The coated article is heat treated sufficiently to cause the Zn-doped zirconium based layer to transform into a Zn-doped zirconium oxide based layer that is scratch resistant and/or chemically durable. The doping of the layer with Zn has been found to improve scratch resistance and/or corrosion resistance.
