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.
