Fight against corrosion in boating

Corrosion is a process that affected much of the water craft in time will the. metals that make up a boat hull develop galvanic corrosion in constant contact with the water. It is therefore boat manufacturers will make use of any material other than glass fibre or wood for building boats. Aluminium is also used, but not without right actions for slow corrosion. Although a slow reduction in an aluminum-hulled vessels seems inevitable, magnesiumlegeringarna can be used to extend the process, and thus extend the life of the boat.

Hull Material
Aluminium magnesiumlegeringarna used in freshwater boat hulls, but most of the hull material consisting of wood or aluminium. The reason is the vulnerability of magnesium outside of freshwater. Magnesium is known for its protective ability. It creates a protective film around itself that serves to prevent corrosion. In fresh water, this is what happens. Magnesium mixed inside the aluminium creates a protective shield around the boat. In salt water, but reacts with acceleration in unstably magnesium corrosion rather than protection of fresh water. The reason is the metal interactions with salt in the water.

Researchers working with magnesium alloy combinations to find a combination that would counteract the salt water of magnesium to build its protective shielding. So far, it is known that iron, nickel, copper and cobalt kick-start corrosion processes more than all other elements.

Magnesium anodes
In order to deflect some of the most corrosive energy on the hull, the boat builders an anode on the hull of a metal which is more corrosive than the material which the hull is made of; that's where magnesium is usually located on the boats. Known as a sacrificial anode, placed the anode on the hull as the ideal location for the electrical current that causes the galvanic corrosion flows through. Corrosion is an electrochemical reaction which attracted to the anode. By placing a sacrificial anode on the hull, creating a protective zone boater on the rest of the boat in the form of a cathode or area of reduced current flow. Apart from the anode, there is very little metal found on the hull of a boat.

In boating, is magnesium's protective and corrosivity positive depending on the type of water boater travelling in Metal forming. a protective force-field of fresh water to divert the corrosive energy, but in the salt water is a similar to a magnetic current. It would be fantastic if researchers found a way to exploit these conflicting powers to create a corrosion-proof hull.
