An example of extreme pitting corrosion is shown below. In this type of corrosion, a corrosive electrolytic solution starts to creep deep into the structure as it corrodes. This type of accelerated corrosion mechanism is ...
WebIn , the forced current cathodic protection system of the ship was modeled, and the influence of the shape and position of the auxiliary anode on the cathodic protection effect was analyzed. In [ 18 ], the forced current cathodic protection system of reinforced concrete is modeled and analyzed, and the parameters such as current output and ... WebCathodic protection ( CP; / kæˈθɒdɪk / ( listen)) 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.
WebImpressed current cathodic protection is also called forced current protection. It provides the required protection current through an external power supply. A method in which a metal to be protected is used as a cathode and a specific material is used as an auxiliary anode to protect the metal to be protected.
