| Abstract | This work is aimed to study mechanism and parameter influencing dealloying of 8Al-8Mn-Cu Manganese Aluminium Bronze (MAB). The results revealed that ?-phase was a corrosion onset site or anode as it contained larger amounts of, highly reactive metals, aluminium manganese and nickel than ?-phase. Since these reactive metals were leached, copper was left behind. This phenomenon leaded to alteration of electrochemical potential thereby the ?-phase turned to be a cathode causing of corrosion propagation to ?-phase anode. In addition amount of chloride ions in service environment affected the dealloying of 8Al-8Mn-Cu MAB in this work. |
