In certain example embodiments, a coated article includes a zirconium nitride inclusive layer before heat treatment (HT). The coated article is heat treated sufficiently to cause the zirconium nitride based layer to transform into a zirconium oxide based layer that is scratch resistant and/or durable. In certain example embodiments, the zirconium nitride and/or zirconium oxide may be doped with F and/or C.

The invention claimed is: 1. A method of making a heat treated coated article, the method comprising: having a coating supported by a glass substrate, the coating comprising a zirconium nitride based layer; and thermally tempering the glass substrate with the zirconium nitride based layer thereon,
The invention claimed is: 1. A method of making a heat treated coated article, the method comprising: having a coating supported by a glass substrate, the coating comprising a zirconium nitride based layer; and thermally tempering the glass substrate with the zirconium nitride based layer thereon, so that the tempering causes the zirconium nitride based layer to transform into a layer comprising zirconium oxide (ZrxOy) where y/x is from about 1.2 to 2.5, and wherein the layer comprising zirconium oxide further comprises fluorine and/or carbon. 2. The method of claim 1, wherein y/x is from about 1.4 to 2.1. 3. A method of making a heat treated coated article, the method comprising: having a coating supported by a glass substrate, the coating comprising a zirconium nitride based layer; and thermally tempering the glass substrate with the zirconium nitride based layer thereon, so that the tempering causes the zirconium nitride based layer to transform into a layer comprising zirconium oxide (ZrxOy) where y/x is from about 1.2 to 2.5, wherein the zirconium nitride based layer further comprises fluorine and/or carbon. 4. The method of claim 3, wherein the layer comprising zirconium oxide further comprises fluorine and/or carbon. 5. The method of claim 1, wherein prior to the tempering, the coating further comprises a layer comprising diamond-like carbon located between the glass substrate and the zirconium nitride based layer. 6. The method of claim 1, wherein prior to the tempering, the coating further comprises a layer comprising diamond-like carbon located on the glass substrate over at least the zirconium nitride based layer. 7. The method of claim 1, wherein prior to and/or after the tempering, the coating further comprises a dielectric layer between the glass substrate and the zirconium nitride based layer. 8. The method of claim 1, wherein the layer comprising zirconium oxide comprises a nanocrystalline cubic lattice structure. 9. The method of claim 1, wherein the layer comprising zirconium oxide comprises from about 30-80% oxygen. 10. The method of claim 1, wherein the layer comprising zirconium oxide comprises from about 50 to 70% oxygen. 11. The method of claim 1, wherein the layer comprising zirconium oxide comprises from about 20-60% Zr. 12. The method of claim 1, wherein the layer comprising zirconium oxide comprises from about 30-55% Zr. 13. The method of claim 1, wherein the layer comprising zirconium oxide comprises from about 30-45% Zr and from about 0-10% N. 14. The method of claim 1, wherein the layer comprising zirconium oxide is an outermost layer of the coated article following heat treatment. 15. The method of claim 1, wherein visible transmission % of the coated article increases by at least 30% due to the tempering. 16. The method of claim 1, wherein the tempered coated article has a transmissive a* value of from-4 to 0, and a transmissive b* value of from-3 to +3. 17. The method of claim 1, wherein the tempered coated article has a visible transmission of at least 70%. 18. The method of claim 1, wherein the coated article after tempering has a visible transmission of at least 70% and a critical scratch load using an alumina sphere of at least about 20 lbs. 19. A method of making a heat treated coated article, the method comprising: having a coating supported by a glass substrate, the coating comprising a layer comprising zirconium nitride; and thermally tempering the glass substrate with the layer comprising zirconium nitride, so that the tempering causes zirconium nitride to transform into a layer comprising zirconium oxide (ZrxOy) where y/x is from about 1.2 to 2.5, and wherein the layer comprising zirconium oxide further comprises fluorine and/or carbon.
