Cathodic protection — (CP) is a technique to control the corrosion of a metal surface by making it work as a cathode of an electrochemical cell. This is achieved by placing in contact with the metal to be protected another more easily corroded metal to act as the… … Wikipedia
Cathodic protection rectifier — Cathodic protection rectifiers are AC powered electrical equipment that provide direct current for impressed current cathodic protection systems.Rectifier units are often custom manufactured and equipped with a variety of features, including oil… … Wikipedia
Cathodic arc deposition — or Arc PVD is a physical vapor deposition technique in which an electric arc is used to vaporize material from a cathode target. The vaporized material then condenses on a substrate, forming a thin film. The technique is can be used to deposit a… … Wikipedia
cathodic protection — noun : the control of the electrolytic corrosion of an underground or underwater metallic structure (as a pipeline) by the application of an electric current in such a way that the structure is made to act as the cathode instead of anode of an… … Useful english dictionary
