What Is Cathodic Protection? What are the Pros & Cons?

WebIn general, when the soil resistivity is low (< 5000 ohm-centimeters) and the current density requirement is low, a sacrificial anode cathodic protection system is selected. … WebMoreover, a sacrificial anode system does not offer the same level precision as modern cathodic protections such as ICCP systems. There is, for instance, no means to check … Cathodic protection is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. 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 instead of the protected metal. For structures such as long pipelines, where passive galvanic cathodic protection is not adequate, an external DC electrical power source is used to … how to stop recording in screenpresso
