A metal rod inserted into a water heater to extend the life of the tank.

Process whereby zinc covers an iron part on a boat to reduce corrosion. Usually placed on a outboard motor on base plate.
An anode made of suitable metal placed in a water heater tank to protect the tank from corrosion. Anodes of metals such as aluminum, magnesium, or zinc are sometimes installed in water heaters and other tanks to control corrosion of the tank. The introduction of the anode creates a galvanic cell in which the magnesium or zinc will go into solution (be corroded) more quickly than the metal of the tank, thereby imparting a cathodic (negative) charge to the tank metal(s) and thus preventing tank corrosion.

Metal parts fitted to the hull of a ship to provide a transfer of ions to the cathodic part of an electrolytic coupling and so protect other parts of the ship that would otherwise waste away through electrolysis.
A sacrificial anode, or sacrificial rod, is a metallic anode used in a cathodic protection where it is intended to be dissolved to protect other metallic components.
