Abstract
A method for the electrochemical plating or marking of metals includes providing a metal surface, providing an electroplating solution at the metal surface, and electroplating the metal surface with the electroplating solution. A top layer of the metal surface comprises an oxide scale. The method can also include masking a portion of the metal surface with a masking material. The electroplating solution can be provided at the metal surface by an electroplating brush, the oxide scale of the metal surface can be comprised primarily of magnetite and hematite, and the material comprising the metal surface can be steel.
