dc.description.abstractAn electrochemical investigation was conducted to evaluate the corrosion behaviour of Iron alloys such as EN-8 and 411143 in absence and in presence of microbes Acidithiobacillus ferrooxidans. Linear polarization technique was employed to measure the Polarization Resistance and corrosion rates of two different ferrous metal samples. Polarization resistance (Rp) values of EN-8 were initially higher in the presence of Acidithiobacillus ferrooxidans than the values of 411143. Growth rate of the Acidithiobacillus ferrooxidans was more and sustained longer period with EN-8 in the presence of media than in the case of alloy ‘411143’. It was observed that there was a 1.5 fold increase in corrosion rate in both the cases of EN-8 and 411143 in the presence of bacteria.High corrosion rates were recorded with the steel 41143 rather than the En-8 with respect to the optical density of the microbes. It was concluded that EN-8 was exhibited high resistance to the microbial attack.en_US
