Abstract: A copper containing component and a manganese containing component are applied onto the surface of a substrate to form a coating having a selected ratio of copper to manganese to form a desired color. For a brown color, the film molar ratio of copper to manganese is above 1; for an amber color, the molar ratio is below 1, and for a blue color the film molar ratio is about 1. Further, color shifting of a multi-component coating upon subsequent heat treatment is minimized or prevented by determining the most mobile species in the coating and then placing a concentration gradient layer of an oxide of that mobile species between the substrate and the coating.

Abstract: The present invention is directed to a method of and apparatus for forming a coating having at least one fade zone over a substrate. The method and apparatus include positioning a coating composition dispenser above a surface of a substrate with the coating composition dispenser oriented to dispense a coating composition spray generally normal to the surface of the substrate.

The coating composition spray and the gas stream are spaced from each other so as to develop an interference effect therebetween adjacent the surface of the substrate. Preferably the substrate is maintained at a temperature which pyrolyzes the coating composition. The interference effect directs the coating composition to deposit over the substrate as a coating having a fade zone.

The coated article can be tempered and/or bent without losing its metallic properties to oxidation.
