🟥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

Replacing sacrificial anodes on your boat is easy. If you can turn a wrench, you can do this job. Here's how. #MaintenanceMonday | BoatUS

Let's understand Cathodic Protection ⚡🛡 Cathodic protection is a technique used to prevent or reduce corrosion of metal structures, such as pipelines, tanks, and offshore platforms. It involves the application of a direct current (DC) to the metal surface to counteract the electrochemical reactions that cause corrosion. Corrosion is an electrochemical process where metals react with their environment, typically in the presence of moisture and oxygen, resulting in the degradation of the metal. I
