The corrosion mechanisms of Cu-7Ni-3Al-1Fe-1Mn (wt.%) alloy in a 3.5% NaCl solution are investigated through a multi-analytical approach. The formation, growth and stable corrosion stage of the stable corrosion layer are reflected by the change of electrochemical response with time. EDS and GI-XRD results show the presence of Cu2(OH)3Cl and Cu2O that are the main corrosion products, with the former predominantly present at topmost corrosion layer, and Cu2O is mainly located in the inner part, followed by aluminum oxide closer to the alloy substrate.
