It is made out of magnesium or aluminum that form around a steel core wire.
I doubt this is useful since this was posted 4 years ago, but carbon anodes have to be replaced in commercial use because they react with the oxygen that is reacts with (or so i think), and therefore the co2 that comes from the carbon and metal oxide in the displacement reaction makes the carbon anodes turn into co2 and therefore these anodes need to be replaced
Aluminum and zinc are close enough not to cause too much trouble. In highly electrolytic solutions there will be a voltage potential between them. Different metals should be avoided if at all possible when in contact with water or solutions.
That's a purely arbitrary convention that goes back to the first experiments with electricity (see Ben Franklin).
Electroplating served a number of functions, such as protecting from corrosion and wear, decoration, and electrical shielding.
negative electrode
Anodes
Zinc anodes offer a sacrificial method of maintaining the steelwork of the pier.. The anodes 'attract' corrosion thereby extending the life and protecting the steel work. (same as on ships hulls etc)

i dont know use rectifier just invert ac to dc and supplied to anodes positive to steel negative
diode
i searched it up and didn't find anything, sorry i couldn't help
This is the anode.
Zinc anodes can help protect buried water tanks or any buried steel structure from external corrosion. The use of zinc anodes protect a structure from corrosion by a principle is known as cathodic protection. Corrosion is an electrochemical reaction where the reaction can be separated into two halves (two half-cell reactions): the anodic and the cathodic reactions. Deterioration (or corrosion) of the metal occurs at the anode. When zinc is in electrical contact with the steel and immersed in the same liquid, the zinc become the anode and the steel structure becomes the cathode. The zine is preferentially corroded, leaving the steel structure protected. To protect a steel tank, the anodes should be buried and evenly distributed around the tank. Deep anodes are sometimes needed to protect tanks with large flat bottoms. The holes around the anode are often filled with carbon to ensure good electrical contact with the ground water. Electric cables need to connect the zinc anodes to the steel. The anodes do not protect against internal corrosion of the tank.

Several applications of indium:- in liquid alloy at r.m. called gallinstan- in aluminium alloy for some anodes- standard in thermometry- vacuum sealing- component of some control rods for nuclear reactors
