Using Cathodic Protection To Control Corrosion In Marine Environments Cathodic protection (cp) can be impressed current cathodic protection, galvanic anode cathodic protection or a combination of both. cathodic protection controls corrosion by supplying direct current to the immersed surface of the structure, thus making the structure a cathode of a cell. Introduction corrosion & accelerated low water corrosion (alwc) introduction to marine cathodic protection (cp) galvanic anodes versus impressed current project examples cp of steel in concrete.
Cathodic Protection Pdf Anode Corrosion 1.0 introduction metallic structures in contact with water, soil, concrete, and moist air are subject to corrosion. cathodic protection (cp) is one of the few methods that successfully mitigates corrosion. it can be applied in any situation where the environment surrounding the metal acts as a conductor for electric current. it has been successfully applied to offshore structures, ships, boats. Introduction cathodic protection the external is applied to the internal the immersed containing vessel from seawater, corrosion. cathodic anode techniques protection, often in conjunction with coatings, can be applied by impressed current, galvanic cathodic or a combination electrolyte protection direct current to the immersed surface to change the steel to potential works by applying to. This document discusses cathodic protection methods for preventing corrosion of marine structures. it describes two main methods: sacrificial anode systems which use more reactive "sacrificial" metals like zinc to corrode instead of the protected structure; and impressed current cathodic protection systems which use an external power source to supply electrons and reduce corrosion. both work. Then, a sample anode plan of a ship is shown. finally, the calculation of a cathodic protection system of a ship is presented using data provided by coating manufacturers and shipyards.
