Decorative article having a white film

摘要

A personal ornament having a white coating layer comprises a base article made of a metal, and a white-colored stainless steel coating layer formed by a dry plating process on at least a part of the surface of the base article. Another personal ornament having a white coating layer comprises a base article made of a nonferrous metal, an underlying plating layer formed on the surface of the base article, and a white-colored stainless steel coating layer formed by a dry plating process on at least a part of the surface of the underlying plating layer. A process for producing a personal ornament having a white outermost layer comprises steps of forming a base article of the personal ornament by machining a metal; washing and degreasing the surface of the base article; cleaning the base article by bombard cleaning in the dry plating apparatus; and forming a white-colored stainless steel coating layer on the base article surface by a dry plating process. Another process for producing a personal ornament having a white outermost layer comprises steps of forming a base article of the personal ornament from a nonferrous metal by machining; washing and degreasing the surface of the base article; forming on the surface of the base article an underlying plating layer by a wet plating process or a dry plating process; cleaning the surface of the underlying plating layer by bombard cleaning in a dry plating apparatus; and forming a white-colored stainless steel coating layer by a dry plating process on the surface of the underlying plating layer. The present invention provides a low-priced personal ornament which has a white-colored inexpensive stainless steel outermost coating layer having a long-term corrosion resistance, and also provides a process for producing the personal ornament.
