Abstract

"During cathodic protection of a corroding metal, electrons are forced into the metal by a sacrificial anode, a battery or a rectifier. These electrons, which constitute the suppressing or external current, are discharged (by H⁺ of the corrosive liquid) on the local cathode of the corroding metal decreasing the emf of the local cells, and, thus, reducing the cell current or the rate of corrosion of the metal. This process was studied in detail by finding out the relationship existing between the cell and suppressing currents. The study was made using two circuits: the cell circuit (representing the local current) and circuit delivering the suppressing current (representing the sacrificial anode). It was found that there is a straight line relationship between suppressing current and the cell current and the inclination of the line depends on the nature of the cathode, surface treatments of cathode, resistance of the cell, the nature and concentration of electrolyte and additives, on the presence of O₂ and gases, temperature, and cathodic polarization behavior acting as resistance overpotential"--Abstract, page ii.
