Effect of bacterial biofilm on 316 SS corrosion in natural seawater by EIS

The electrochemical behavior of AISI 316 stainless steel in natural seawater collected from Canary Archipelago was investigated. A comparative study on a large number of samples immersed during three weeks in this environment with and without sulfate-reducing bacteria (SRB) was made. Open circuit potential measurements, cyclic polarization, Scanning Electron Microscopy (SEM) and Electrochemical Impedance Spectroscopy (EIS) were used. The obtained results permitted an interpretation of the contribution of biofilms to corrosion of stainless steel and a mechanism of the process is checked.
