Dissolve Evenly Magnesium Anodes OEM For Cathodic Protection
Dissolve evenly Magnesium Anodes OEM For Cathodic Protection
Introduction:
Cathodic protection connects a metal (steel) at risk to a sacrificial metal that corrodes in place of the metal. The technique of providing cathodic protection of steel protects the metal by providing a highly reactive metal that can act as an anode and provide free electrons. By introducing these free electrons, the active metal sacrifices its ions and prevents corrosion of the less active steel.
The magnesium anode we provide has a negative potential and generates a large amount of electricity per unit mass, which is an ideal sacrificial anode material.It is suitable for cathodic protection of metal structures in media such as soil, fresh water and sea water.

How magnesium anodes work
Magnesium anodes protect steel through sacrificial electrochemistry. Magnesium is negatively charged relative to steel. When the magnesium rod is connected to the steel tank by electrical conductors, the steel tank is then filled with water, and the current will continuously flow through the water between the magnesium rod and any exposed steel areas on the wall. The circuit is completed back to the magnesium rod through the water tank. This protective current is generated by magnesium releasing ions, which can lead to corrosion in the anode area. This type of galvanic protection is called "sacrificial"; the magnesium rod (anode) corrodes rather than the can (cathode). This principle of electrolytic corrosion control is called "cathodic protection". Because the cathode surface does not rust, the tank is protected.
Applications:
Cathodic protection is often used to mitigate corrosion damage to active metal surfaces. It is used worldwide to protect pipelines, water treatment plants, above and submerged storage tanks, ships and hulls, offshore production platforms, concrete structures and rebar in docks, among others.
