Abstract

Anodized titanium with its interference colors, its appearances and its light, is undoubtedly of great appeal to the field of architecture and to all ramifications of design, to visual communication and to the world of fashion. On its surface, it is possible to create a visionary world of colors, perfectly controlled by the imposition of determined anodizing parameters and surface conditions. This article presents one of the applications of anodized titanium, which most earns general interest nowadays in the designers' world, that is, the production of colored titanium jewels. Since titanium is considered a seminoble metal, its use is mainly directed to small series production: therefore, a good know-how giving high reliability of the anodic coloring process is required. The chosen procedure will be described, together with a full characterization of the obtained interference colors. © 2011 Wiley Periodicals, Inc. Col Res Appl, 2012
