WebThe positively charged zinc ions at the zinc (anode) surface react with negatively charged hydroxyl ions from the electrolyte and zinc is slowly consumed, providing sacrificial protection for the steel. This phenomenon that prevents corrosion of the steel, i.e. the cathode, is known as cathodic protection. WebGalvanizing. Prepared items are galvanized by immersion in molten zinc. On immersion in the galvanizing bath the steel surface is completely covered by the molten zinc, which reacts with the steel to form a series of zinc-iron alloy layers. The thickness of these layers is determined principally by the mass of the steel being galvanized.
