A method of making a coated article (e.g., window unit), and corresponding coated article are provided. A layer of or including diamond-like carbon (DLC) is formed on a glass substrate. Then, a protective layer is formed on the substrate over the DLC inclusive layer. During heat treatment (HT), the protective layer prevents the DLC inclusive layer from significantly burning off. Thereafter, the resulting coated glass substrate may be used as desired, it having been HT and including the protective DLC inclusive layer.

A method of making a coated article, the method comprising: providing a glass substrate, forming a layer comprising diamond-like carbon (DLC) on the glass substrate, forming a layer comprising zirconium on the glass substrate over the layer comprising DLC, forming a solar control multi-layer coating including at least one layer comprising silver (Ag) and/or nickel chrome (NiCr) and at least one dielectric layer onto a surface of the glass substrate, the layer comprising Ag and/or NiCr being located between at least the glass substrate and the dielectric layer, so that the solar control multi-layer coating and the layer comprising DLC are formed on opposite sides of the glass substrate, heat treating the glass substrate with each of the solar control multi-layer coating, the layer comprising DLC and the layer comprising zirconium thereon at least at a time when the heat treating begins, and wherein the heat treating comprises heating the glass substrate using at least temperature(s) of at least 580 degrees C., in an atmosphere including oxygen, for a time period sufficient for bending and/or thermally tempering the glass substrate. 2. The method of claim 1, wherein the layer comprising DLC is formed on the glass substrate via an ion beam, and wherein carbon atoms thereof are subimplanted into the glass substrate. 3. The method of claim 1, wherein the layer comprising zirconium is at least partially formed on the glass substrate via sputtering. 4. The method of claim 1, wherein the coated article comprises either a vehicle window or an insulating glass (IG) window unit. 5. The method of claim 1, wherein the layer comprising DLC comprises amorphous DLC and has more sp3 carbon-carbon bonds than sp2 carbon-carbon bonds. 6. The method of claim 1, wherein the layer comprising DLC has an average hardness of at least 10 GPa. 7. The method of claim 1, wherein the layer comprising zirconium comprises a carbide of Zr. 8. A method of making a coated article, the method comprising: providing a glass substrate, forming each of a layer comprising diamond-like carbon (DLC) and a layer comprising zirconium on one side of the glass substrate, forming a solar control multi-layer coating including at least one layer comprising silver (Ag) and/or nickel chrome (NiCr), and at least one dielectric layer, onto another side of the glass substrate, the layer comprising Ag and/or NiCr being located between at least the glass substrate and the dielectric layer, so that the solar control multi-layer coating and the layer comprising DLC are formed on opposite sides of the glass substrate, heat treating the glass substrate with each of the solar control multi-layer coating, the layer comprising DLC and the layer comprising zirconium thereon at least at a time when the heat treating begins, and wherein the heat treating comprises heating the glass substrate using at least temperature(s) of at least 580 degrees C., in an atmosphere including oxygen, for a time period sufficient for bending and/or thermally tempering the glass substrate. 9.
