ABSTRACT:
An underlayer of at least one a carbonitride of titanium, zirconium, hafnium or vanadium or hafnium nitride may be under a surface layer at least containing gold or on a still-undermore decorative article, and preferably both. It has a brilliance approximating that of gold so that, when appropriately color matched to the surface layer, it disguises spots of the surface layer worn away in use of the article. The underlayer and surface layer may be deposited in a cathode vaporization process from corresponding metallic cathode targets in appropriate neutral or reactive atmospheres.
