RESISTANCE OF THE CATHODE DEPOSIT AS A PARAMETER IN THE CALCULATION OF THE CATHODIC PROTECTION OF SHIPS

The favorable effect of electrochemical protection for a paint coating is explained by the absence of corrosion products on the surface of the metal under the layer of paint; such corrosion products distend the film of paint which promotes scaling and peeling; the effect is explained also by the formation, in the pores of the paint and in its damaged sections, of a cathode deposit, which sets up an additional ohmic resistance and increases the overall polarizability of the hull. The cathode deposit exhibits good insulating properties and adhesion to the metal. Paint coatings provide good intermediate protection and power savings during the initial protection period.
