Abstract
A one side plated metal of excellent appearance and quality can be obtained by dipping the material into a plating bath. In this case, one side of the material is oxidized just before it enters the bath so as to form an oxide film on that side and leave it unplated. As soon as it is pulled up from the bath it is maintained under reducing atmosphere so as to prevent adherence of the plating metal to the oxide film.
