  • Publication number: 20180127307
    Abstract: In certain example embodiments, a coated article includes a carbon-doped zirconium based layer before heat treatment (HT). The coated article is heat treated sufficiently to cause the carbon-doped zirconium oxide and/or nitride based layer to result in a carbon-doped zirconium oxide based layer that is scratch resistant and/or chemically durable. The doping of the layer with carbon (C) has been found to improve wear resistance.
