The effect of and on the corrosion behaviour of 70Cu-30Ni alloy.

This work investigated the effect of () and () on the microbiologically influenced corrosion (MIC) behaviour of 70Cu-30Ni alloy using surface analysis and electrochemical techniques. The results demonstrated that the mixed medium containing and further accelerated the MIC of 70Cu-30Ni alloy compared to the single species medium. The addition of exogenous pyocyanin (PYO) to the medium increased the maximum pit depth on 70Cu-30Ni alloy from 5.
