Abstract:
1. A method of making a heat treated coated article, the method comprising: forming at least one layer comprising diamond-like carbon (DLC) on a glass substrate; forming a removable protective film on the glass substrate over at least the layer comprising DLC, the removable protective film comprising first and second inorganic layers, the first inorganic layer comprising zinc oxide and nitrogen and being located between the layer comprising DLC and the second inorganic layer; heat treating the glass substrate with the layer comprising DLC and the protective film thereon so that during the heat treating the protective film prevents significant burnoff of the layer comprising DLC, wherein the heat treating comprises heating the glass substrate to temperature(s) sufficient for thermal tempering, heat strengthening, and/or heat bending, and wherein the first inorganic layer comprising zinc oxide and nitrogen, and the second inorganic layer, substantially remain on the glass substrate protecting the layer comprising DLC during said heat treating; and removing the first inorganic layer comprising zinc oxide and nitrogen, and the second inorganic layer, after said heat treating.
