Abstract
In forming a protective coating of zinc on metal surface of iron, steel, copper or the like, a neutral solution containing a zinc compound is deoxidized and, making the metal immersed therein or in contact therewith the cathode of a cell, a current is passed therethrough to cause deposition of zinc on the metal surface. The metal to be protected may, for example, be in the form of a metal structure, as a ballast tank or condenser of a ship.
