Electroplating

Electrolytically applied zinc and zinc alloy coatings (zinc-iron, zinc-nickel) through electrochemical deposition on the object that is to be coated. With the electroplating process, current is produced in an electrolytic bath.

Located at the positive pole (anode) is the metal (e.g., zinc, iron or nickel) that is to be applied; located at the negative pole (cathode) is the object that is to be plated.
