Abstract
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.
Claims28
A method of making a heat treated coated article, the method comprising:
- having a coated article including a coating supported by a glass substrate, the coating comprising a tungsten-doped layer comprising an oxide and/or nitride of zirconium;
- and
- thermally tempering the coated article, including the glass substrate and the tungsten-doped layer comprising an oxide and/or nitride of zirconium, so that after the tempering a layer comprising tungsten-doped zirconium oxide is provided on the glass substrate.
A method of making a heat treated coated article, the method comprising:
- having a coated article including a coating supported by a glass substrate, the coating comprising a tungsten-doped layer comprising an oxide and/or nitride of zirconium;
- and
- heat treating the coated article, including the glass substrate and the tungsten-doped layer comprising an oxide and/or nitride of zirconium, so that after the heat treating a layer comprising tungsten-doped zirconium oxide is provided on the glass substrate.
A method of making a heat treated coated article, the method comprising:
- having a coated article including a coating supported by a glass substrate, the coating comprising a layer comprising tungsten and/or tungsten carbide that directly contacts a layer comprising an oxide and/or nitride of zirconium;
- and
- thermally tempering the coated article, including the glass substrate and the layer comprising tungsten and/or tungsten carbide and the layer comprising an oxide and/or nitride of zirconium, so that migration occurs between the layers during said tempering and after the tempering a layer comprising tungsten-doped zirconium oxide is provided on the glass substrate.
