Resumen:
The influence of Ni as an alloying element in the improvement of the corrosion resistance of copper-base alloys, using boric-borate buffer (pH=7.8) as electrolyte, was studied. Electrochemical and spectrophotometrical techniques were combined to account for the presence of cuprous oxide. When the nickel content increased and reached 30%, the composition of the film changed noticeably by the incorporation of Ni(II) compounds.
