Abstract Cathodic protection is an electrochemical means of corrosion control in which the oxidation reaction in a galvanic cell is concentrated at the anode, which suppresses corrosion of the cathode in the same cell. This article provides a detailed discussion on the fundamentals and types of...

...-aluminum and aluminum-magnesium that have a corrosion potential less noble than that of steel. When the steel surface is covered with such metals, it does not corrode, even if pores exist in the coating. The coating is acting as a sacrificial anode, and the steel is cathodically protected. The term...

... corrosion behavior of carbon steel is less sensitive to water quality. This is due to the fact that anodic products on carbon steels are not protective, and therefore, corrosion rate is controlled by the cathodic process, that is, the supply of dissolved oxygen. The behavior of carbon steel in soil...
