CORROSION RESISTANCE OF CLAD STEEL SHIPS PLATES
The aims of this project are concerned with assessing the effects of damage to a copper-nickel clad steel hull and whether any steel exposed can be prevented from corroding by the use of cathodic protection. The tests have shown that the presence of the noble metal -- copper-nickel -- causes the corrosion of steel to be much faster than would otherwise be the case. Cathodic protection is capable of preventing this although it would be a drain on the ship's power generating capacity. Cathodic protection if used for a long period in fairly static water would also negate the anti-fouling property of the copper-nickel although, once the damage was repaired and cathodic protection removed, this property would be fully restored. The exposed steel causes a significant change in the electrochemical potential of the copper-nickel and this effect could be used to detect whether any damage has occurred.
