Principle

Technically, corrosion protection by zincking is attained by two different processes: By hot galvanizing, or by electroplating, i.e. by galvanic (electrochemical) deposition of zinc from a solution of zinc, in which the iron object to be treated is hung as the cathode. The electroplating procedure consumes considerably less zinc per square meter of surface than hot galvanizing, and is therefore now the preferred procedure.
In this experiment, a piece of sheet iron is coated electrochemically with zinc, and subsequently a long term experiment is carried out to demonstrate the protective action of this zincking against corrosion.
