摘要： A decorative article having a while film, comprising a white-tone stainless steel film formed on at least part of a surface of a metallic or non-metallic base material (in the case of a non-metallic base material, a backing plated film is additionally provided on the base material) by a dry plating method. A production method for a decorative article having a white film, characterized by comprising a base material shaping process by machining of metal or non-metal, a process of cleaning/degreasing the surface of the base material, a process of bombard-cleaning the base material in a dry plating device (in the case of non-metal, a process of forming a backing plated film on the surface of the base material by a wet or dry plating method after cleaning/degreasing the base material, and a bombard cleaning of the formed film), and a process of forming a white-tone stainless steel film on the surface of the base material (film) by a dry plating method, whereby providing a low-cost decorative article having a white-tone stainless steel film excellent in extended-time corrosion resistance as the outermost-layer film, and a production method therefor.

摘要： A golden ornament includes a base material; a Ti coating film which is formed on a surface of the base material in an atmosphere of an inert gas other than nitrogen and whose Ti atom content is constant in the thickness direction; a TiN gradient coating film which is formed on the Ti coating film and whose N atom content has a gradient in the thickness direction; a TiN coating film which is formed on the TiN gradient coating film and whose contents of Ti atoms and N atoms are constant in the thickness direction; an Au-TiN mixture gradient coating film which is formed on the TiN coating film and whose Au atom content has a gradient in the thickness direction; and an Au-TiN mixture coating film which is formed on the Au-TiN mixture gradient coating film and whose contents of Au atoms, Ti atoms, and N atoms are constant in the thickness direction. The golden ornament may further include an Au coating film or an Au alloy coating film which is formed on the Au-TiN mixture coating film and whose Au atom content is constant in the thickness direction.
