SURFACE TREATMENT METHOD FOR ORNAMENT, AND THE ORNAMENT

摘要

PROBLEM TO BE SOLVED: To provide an ornament which has an excellent aesthetic appearance, and a surface treatment method for the ornament. SOLUTION: The surface treatment method contains stages (3a, 3b) where a first substrate 41 is formed at least on a part of the surface of a base material 2; a stage (3c) where a second substrate 42 is formed thereon; a stage (3d) where a third substrate 43 is formed thereon; and a stage (3e) where a covering layer 3 consisting of a stainless steel is formed at least on a part of the third substrate 43 by a dry plating method. The second substrate 42 is a buffer layer relaxing the potential difference between the first substrate 41 and the third substrate 43. The average thickness of the covering layer 3 is preferably 0.5 to 2.5μm.
