Disclosed is a coated article, for example an architectural transparency, or a vehicular transparency, or a reflecting article, as a decorative article. The article has a substrate, e.g., a substantially transparent substrate. The substrate has an optical coating on a surface thereof. The coating is a bilayer dielectric thin film having a thickness corresponding to a constructively interfering function of a wavelength of interest. The bilayer thin film is a metallic layer, which serves as an adhesion layer, with a dielectric atop the metallic layer which is a compound of the metal forming the metallic layer.

Transparency having a second surface multilayer decorative coating

A coated stainless steel article and a method of preparing the article are disclosed. The coating is a plasma chemical vapor deposited coating, formed from a plasma of nitrous oxide, a silane, and an energy transfer agent (such as He, Ar). The resulting coating is adherent, corrosion resistant, and has a thickness sufficient to mask and cover the features of the stainless steel substrate, and to provide a pitting potential (in 3.5% NaCl) of greater than 600 millivolts, a J.I.S. 8502 (1982) versus a saturated calomel electrode a salt spray test rating in 5% NaCl-0.02% hydrogen peroxide of at least B.

Plasma chemical vapor deposition SiO.sub.2-x coated articles and plasma

A coated article, for example an architectural transparency, including a vehicular transparency, or a reflecting article, as a decorative article. The article has a substrate, e.g., a substantially transparent or substantially opaque substrate. The substrate has an optical coating on it, that is a coating having a thin film of an oxide of a transition metal, the thin film having a thickness corresponding to a constructively interfering function of a wavelength of interest. The optical coating, having a thin film of a transition metal, enhances the reflectivity of some wavelengths of the visible portion of the electromagnetic spectrum and the reflectivity of other wavelengths of the visible portion of the electromagnetic spectrum.
