The Importance of Zinc Anodes in Boats

The Galvanic corrosion often occurs in the boat which leads to affect the functioning of the boat. To solve this issue zinc anodes can be used. The zinc anodesu2019 surface determines the capacity of the protection it can provide. <br><br>Aluminium anodes can also be used but it is more expensive than zinc anodes. Regular zinc anode replacement can protect it from the galvanic corrosion.<br><br>To know more about the importance of zinc anodes in boats, kindly visit here<br>https://barnaclebusters.com/importance-zinc-anodes-boats-change/<br><br>

  1. The Importance of Zinc Anodes in Boats

  2. When two different types of metal are electrically or physically connected, and then immersed in seawater, the metal becomes a battery. Some form of electrical current is now flowing through this battery. Electrons that created this current are powered by one of the metals giving up it’s metal ions to the ocean water.

  3. In boats, galvanic corrosion usually occurs between a bronze or aluminum propeller that sits on a stainless steel shaft. Galvanic corrosion is counteracted when a third metal, that’s even faster to give up it’s electrons, is added to the circuit. This piece of metal is referred to as the sacrificial anode. This sacrificial anode is usually made up of zinc. Due to this fact, most boaters just refer to the sacrificial anode as the zinc, or zincs.

  4. Zinc should be replaced by the time half of the anode has been lost to corrosion. If you find yourself having to replace the zinc anode more than once a year, than you need an anode with more weight. There are alternative anodes to protect metal hardware on the boat from galvanic corrosion besides zinc. One that is becoming increasingly popular, and is sure to surpass zinc anodes is aluminum anodes.
