Cathodic protection and sacrificial anode are closely related concepts, but they are not exactly the same thing.

Cathodic protection refers to a method of protecting metal surfaces from corrosion by making them the cathode of an electrochemical cell. This is achieved by connecting the metal surface to a more easily corroded metal (known as the sacrificial anode), which is connected to an electrical circuit. The sacrificial anode corrodes preferentially to the metal surface it is protecting, effectively «sacrificing» itself to protect the metal.

A sacrificial anode, also known as a galvanic anode, is a type of cathodic protection. It is a metallic alloy that is designed to corrode preferentially to the metal it is protecting. When a sacrificial anode is connected to the metal it is protecting and is immersed in an electrolyte, the sacrificial anode corrodes, creating an electrical current that flows between the anode and the metal it is protecting. This creates an electrochemical reaction that effectively «sacrifices» the anode to protect the metal.

Sacrificial anodes are often used in cathodic protection systems for ships and boats, as well as for other underwater metal structures such as pipelines and oil and gas platforms. These systems are also known as marine growth prevention system (MGPS) as it prevents not only corrosion but also marine organisms from attaching themselves to the metal surface.
