| Abstract: | Chloride ions can play a stimulating or an inhibitive role on the occurrence of the stress corrosion cracking (SCC) of Al-brass in acidic sulphate solutions depending upon their concentration, the pH and the Cu2+ content of the electrolyte. The stimulating effect is observed either in environmental conditions in which competition between the precipitation of Cu2O and CuCl can occur or in conditions in which Cu2O is thermodynamically stable but the presence of a critical amount of Cl− induces an alteration of its defect structure. The inhibiting effect is observed at high Cl− concentrations where CuCl is the prevailing stable phase. |
