Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathodic side of an electrochemical cell. The simplest method to apply CP is by connecting the metal to be protected with another more easily corroded metal to act as the anode of the electrochemical cell
Definition: Cathodic protection (also known as CP) is a technique used to control the corrosion of a metal surface by making it the cathodic side of an electrochemical cell. The simplest and easiest method to apply cathodic protection is by connecting the metal to be protected with another metal that is a more easily corroded metal to act as the anode of the electrochemical cell. (The anode is the electrode where electricity moves into)
