🟥SUBJECT: SACRIFICIAL ANODES (ANTI-CORROSION) Sacrificial anodes on a ship are metal devices used in cathodic protection to prevent corrosion of the ship’s hull, propeller, rudder, and other underwater metal parts. Sacrificial anodes are made of a more reactive metal (usually zinc, aluminum, or magnesium) than the steel of the ship's hull. When the ship is in seawater, which acts as an electrolyte, electrochemical reactions cause the more reactive metal (the anode) to corrode instead of the les
