The Cathodic Protection Process:



Cathodic protection is a corrosion prevention technique used to protect metal structures and surfaces from deterioration caused by electrochemical reactions. Corrosion occurs when metal surfaces come into contact with corrosive environments, such as moisture, saltwater, or certain chemicals, resulting in the breakdown of the metal and eventual damage or failure.

Cathodic protection works by making the metal structure or surface the cathode of an electrochemical cell, thereby reducing its corrosion rate. It achieves this by introducing an external electrical current to counteract the natural corrosion process. There are two primary types of cathodic protection:

Sacrificial Cathodic Protection: In this method, sacrificial anodes made of a more reactive metal, such as zinc or magnesium, are connected to the metal structure to be protected. When the corrosive environment attacks the metal, the sacrificial anodes corrode sacrificially instead, releasing electrons that neutralize the electrochemical reactions at the protected metal surface.

Impressed Current Cathodic Protection: This method involves using an external power source, such as a rectifier, to provide a controlled electrical current to the metal structure. The current is directed towards the structure, making it the cathode, and slowing down the corrosion process. This system typically uses inert anodes, such as titanium or mixed metal oxide (MMO) anodes, which do not corrode.

Cathodic protection is commonly employed to protect a wide range of metal structures, including pipelines, underground storage tanks, offshore platforms, ship hulls, piers, and steel-reinforced concrete structures. It is particularly beneficial in environments where corrosion rates are high, such as in marine environments or industrial facilities.
