METHOD OF MAKING HEAT TREATED COATED ARTICLE USING CARBON BASED COATING AND PROTECTIVE FILM

摘要

A method of making a heat treated (HT) substantially transparent coated article to be used in shower door applications window applications tabletop applications or any other suitable applications. For example certain embodiments relate to a method of making a coated article including a step of heat treating a glass substrate coated with at least layer of or including carbon (e.g. diamond like carbon (DLC)) and an overlying protective film thereon. The protective film may be of or include both (a) an oxygen blocking or barrier layer and (b) a release layer with the release layer being located between at least the carbon based layer and the oxygen blocking layer. The release layer is of or includes zinc oxynitride (e.g. ZnON). Following and/or during heat treatment (e.g. thermal tempering or the like) the protective film may be entirely or partially removed. Other embodiments of this invention relate to the pre HT coated article or the post HT coated article.
