HEAT TREATABLE COATED ARTICLE WITH TUNGSTEN-DOPED ZIRCONIUM BASED LAYER(S) IN COATING

摘要

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