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