Cathodic protection - Wikipedia

Cathodic protection (CP; / k æ ˈ θ ɒ d ɪ k / ()) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode.The sacrificial metal then corrodes instead of the protected metal.
