Effect of the sea water components in the pitting corrosion of copper
Keywords:Copper, Sea water, Pitting, Localized corrosion
Copper is the main component in Cu-Ni alloys recommended for sea water applications. This work presents the electrochemical behaviour of copper in presence of different sea water components and its influence on the corrosion attack. The combined action of chloride and sulphate ions are the main responsible factor for the localized corrosion attack in the form of pitting. A significant parabolic relation exists between the critical pitting potential (Ep) and the weight ratio of chloride to sulphate (Cl-/SO42-) ions. Therefore sulphate ions are an important component for pitting corrosion of copper.
