摘要： In a titanium nitride-based optical coating, the structural stability of the coating is enhanced by providing a damage-retardation base layer (16) between the titanium nitride layer (18) and a substrate (12). Where the optical coating is to provide solar control, the titanium nitride layer is selected primarily for achieving desired optical characteristics, while the thickness of the damage-retardation layer is selected primarily for achieving desired optical characteristics, while the thickness of the damage-retardation layer is selected primarily for achieving desired mechanical characteristics. The damage-retardation layer is formed of a grey metal, with nickel chromium being the preferred metal. The grey metal layer reduces the likelihood that the titanium nitride layer will crack. The tendency of such a layer to crack and form worm tracks is further reduced by exposing the substrate to a plasma preglow (88) and/or by using a slip agent (14) on the side of the substrate on which the layers are to be formed.
