galvanic protection
1Galvanic corrosion — This new manifold for water meters has replaced the old one after 4 years of use, having been connected directly to a copper pipe in the building (0.85 V of potential difference, see the point of corrosion in the bottom left). With a PVC battery… …
2Galvanic anode — A galvanic anode, a type of sacrificial anode, is one of the main components of a galvanic cathodic protection system used to protect metals from corrosion, by the use of a metal electrode which is itself consumed instead in an anodic oxidation… …
3Cathodic 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… …
