Abstract

Corrosion inhibition, O2 reduction and methanol oxidation activities of biofilm (BF) covered SS304 were observed by potentiostatic and potentiodynamic measurements. Corrosion inhibition character of BF grown in Black sea water can be clearly seen in pitting and activation region in alkaline environment. And in highly acidic environment, corrosion inhibition can be seen by anodic dissolution peak shift. O2 reduction and methanol oxidation can be observed by the increase in negative currents for the potential values less than -0.6V vs. SCE and by the increase in positive currents greater than 0.4 V vs. SCE.
