WebThe corrosion current of the anode material is the cathodic protection current for the steel. The current flows through the electrolyte onto the steel, controlling its corrosion. The current returns to the anode in the metallic circuit. You may have heard the term ‘sacrificial anodes’. However, though this terminology describes the anode ... WebGalvanized surface with visible spangle. Galvanization or galvanizing ( also spelled galvanisation or galvanising) [1] is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten zinc. WebCorrosion happens when a metal continues to oxidise.
