The corrosion failure analysis of Ni–Cu alloy coatings in Nutrient Broth medium and in the
presence of two bacteria: Aeromonas salmonicida and Delftia acidovorans, isolated from
water pipe system, has been studied using electrochemical techniques. According to EIS
data, the low Rct values of Ni–Cu alloy coatings after bacteria incubation indicated that the
metabolic products maybe accelerate corrosion. In addition the pH values of the medium did
not change throughout the experiment; however, after immersion the pH value decreased for …
