  • Patent number: 8790783
    Abstract: Certain example embodiments relate 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, and methods of making the same. In certain cases, at least one layer of the coating is of or includes nickel and/or titanium (e.g., NixTiyOz). The provision of a layer including nickel titanium and/or an oxide thereof may permit a layer to be used that has good adhesion to the IR reflecting layer, and reduced absorption of visible light (resulting in a coated article with a higher visible transmission). When a layer including nickel titanium oxide is provided directly over and/or under the IR reflecting layer (e.g., as a barrier layer), this may result in improved chemical and mechanical durability. Thus, visible transmission may be improved if desired, without compromising durability; or, durability may simply be increased.

    Abstract: A housing includes a substrate, a transition layer disposed on the substrate, and a color layer disposed on the transition layer. The transition layer is a layer of titanium-nitride and M-nitride, wherein the M is chromium, aluminum, or silicon. The color layer is a titanium-aluminum-nitride layer. The color layer provides the appearance of enamel on the exterior of the housing. The transition layer enhances the hardness of the housing. An electronic device using the housing is also described.
