Abstract
A method is provided for making a coated article including an anti-etch layer(s) that is resistant to attacks by at least some fluoride-based etchant(s) for at least a period of time. In certain example embodiments, an anti-etch layer(s) is provided on a glass substrate in order to protect the glass substrate from attacks by fluoride-based etchant(s). In certain example embodiments, the anti-etch layer(s) is formed using at least one ion beam (possibly in combination with at least one sputtering target). In certain embodiments, a diamond-like carbon (DLC) inclusive layer(s) may be provided over and/or under the anti-etch layer.
Claims8
A window for use in a bus, train and/or vehicle, the window comprising:
- a glass substrate, and a coating supported by the glass substrate of the window for use in the bus, train and/or vehicle, the window having a visible transmission of at least about 30%;
- wherein the coating comprises a first layer located directly on an contacting the substrate, and an anti-etch layer located over and contacting the first layer,
- wherein the anti-etch layer comprises one or more of:
- silicon carbide nitride, hydrogenated silicon carbide nitride, zirconium oxycarbide, zirconium carbide, hydrogenated zirconium oxycarbide, and/or hydrogenated zirconium carbide.
