Impressed Current Cathodic Protection

Cathodic protection is a technique used to control the rate of corrosion of a metal surface, usually a piece of equipment used in the home or a larger piece of industrial equipment. The system works by turning the surface of the metal itself into the cathode of an electrochemical cell. In simple terms, this means connecting the piece of metal which is to be preserved to a lesser, unprotected, piece of metal which is to be “sacrificed” to corrosion.

Where Is Cathodic Protection Most Commonly Used?

As noted above, systems of cathodic protection are used in all manner of industrial and home use applications. For example, the steel pipes in most home plumbing systems, as well as hot water heaters, are commonly treated with cathodic protection in order to safeguard them from rusting out...
