"Electroetching is a metal etching process that involves the use of a solution of an electrolyte, an anode, and a cathode. The metal piece to be etched is connected to the positive pole of a source of direct electric current. A piece of the same metal is connected to the negative pole of the direct current source and is called the cathode. In order to reduce unwanted electrochemical effects, the anode and the cathode should be of th… " - Galvanic etching
