METHOD OF MAKING HEAT TREATED AND ION-BEAM ETCHED/MILLED COATED ARTICLE USING DIAMOND-LIKE CARBON (DLC) PROTECTIVE FILM.

摘要

There is provided a method of making a heat treated (HT) coated ar¬ ticle to be used in shower door applications, window applications, or any other suitable applications where transparent coated articles are desired. For example, certain embodiments of this invention relate to a method of making a coated article, the method comprising: provid¬ ing a glass substrate including first and second major surfaces, the first major surface being exposed to a tin bath during fabrication of the glass substrate and the second major surface being opposite the first major surface and being acid etched; ion beam treating the first major surface of the substrate so as to remove a surface portion of the substrate, the surface portion comprising one or more of tin, tin oxide and/or surface contaminants; disposing a zirconium-inclusive layer on the first major surface following said ion beam treating; and disposing a layer comprising diamond-like carbon (DLC), directly or in¬ directly, on the zirconium-inclusive layer; wherein the glass substrate with the zirconium-inclusive layer and the layer comprising DLC is heat treatable at a temperature sufficient for thermal tempering, heat strengthening, and/or heat bending so as to cause burn off of the lay¬ er comprising DLC but without also causing significant burn off of the zirconium-inclusive layer.
