HEAT TREATABLE COATED ARTICLE WITH ZINC-DOPED ZIRCONIUM BASED LAYER IN COATING

摘要

In certain example embodiments, a coated article includes a Zn-doped zirc onium based layer before heat treatment (HT). The coated article is heat tre ated sufficiently to cause the Zn-doped zirconium based layer to transform i nto 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 improv e scratch resistance and/or corrosion resistance.
