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. [1] 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 ...
Cathodic Protection: Definition, Working Principles, Types, …
Cathodic Protection is an industrial technique for controlling metallic corrosion. Cathodic protection is commonly used on buried and submerged metallic structures like pipelines, underground storage tanks, locks, subsea equipment, offshore floaters, harbors, and ship hulls.
Cathodic Protection—What is it and how does it work? - Matcor, …
Cathodic protection (CP) is an electro-chemical process that slows or stops corrosion currents by applying DC current to a metal. When applied properly, CP stops the corrosion reaction from occurring to protect the integrity of metallic structures.
