About Cathodic Protection
Metal that has been extracted from its primary ore (metal oxides or other free radicals) has a natural tendency to revert to that state under the action of oxygen and water. This action is called corrosion and the most common example is the rusting of steel.
Cathodic protection is a procedure used to protect an object from corrosion by making it a cathode.To make a structure a cathode, for example a pipeline or tank, you have to attach an anode or impressed current system to it. The structure and protection apparatus both have to be electrically connected through an electrolyte such as soil or water.
The main advantage of cathodic protection over other forms of anti-corrosion treatment is that it is applied simply by maintaining a dc circuit and its effectiveness may be monitored continuously. Cathodic protection is commonly applied to a coated structure to provide corrosion control to areas where the coating may be damaged. It may be applied to existing structures to prolong their life
