DECORATIVE PART AND PROCESS FOR PRODUCING THE SAME

摘要

A decorative part and a process for producing the decorative part. A first nitride layer containing at least one metal selected among hafnium, titanium, and zirconium is formed on the surface of a decorative part comprising a soft base made of a material selected among stainless steel, titanium and titanium alloys, brass, etc., and a second nitride layer containing at least one metal which is selected among hafnium, titanium, and zirconium and is different from that in the first nitride layer is formed on the first nitride layer to thereby form a primer layer. A multilayered hardened layer including a gold alloy layer is further formed as a finish layer on the primer layer. Thus, a golden decorative part having high hardness, high marring resistance, and high corrosion resistance is obtained which neither is marred by impact nor corrodes. Even when the outermost coating layer of the golden decorative part is marred, the mar is less apt to be recognized with the naked eye. The golden decorative part has a golden colour tone which is bright and gives a high-grade feeling. It can hence maintain the beautiful appearance of a decorative article over long.
