In certain example embodiments, a coated article includes respective layers including hydrogenated diamond-like carbon (DLC) and zirconium nitride before heat treatment (HT). During HT, the hydrogenated DLC acts as a fuel which upon combustion with oxygen produces carbon dioxide and/or water. The high temperature developed during this combustion heats the zirconium nitride to a temperature(s) well above the heat treating temperature, thereby causing the zirconium nitride to be transformed into a new post-HT layer including zirconium oxide that is very scratch resistant and durable.

This application relates to a coated article including at least one infrared (IR) reflecting layer of a material such as silver or the like in a low-E coating. In certain embodiments, at least one layer of the coating is of or includes zirconium oxide (e.g., ZrO₂) or zirconium silicon oxynitride (e.g., ZrSiO_xN_y). When a layer comprising zirconium oxide or zirconium silicon oxynitride is provided as the uppermost or overcoat layer of the coated article (e.g., over a silicon nitride based layer), this results in improved chemical and heat stability in certain example embodiments. Coated articles herein may be used in the context of insulating glass (IG) window units, vehicle windows, or in other suitable applications such as monolithic window applications, laminated windows, and/or the like.

A method of making a stick resistant cook surface or cooking vessel having the stick resistance in which a hard substrate metal is treated by mechanical buffing/polishing and/or by electropolishing to a high luster surface finish of less than 20 microinches and then coated with a layer of a ceramic nitride, such as zirconium nitride. The electropolishing step is particularly suited for treating non-round shapes or deep drawn cooking vessels having high side walls, such as pots and pans, or square or rectangular shapes which are otherwise difficult to mechanically buff in the interior due to the side wall geometry and/or corners.
