Abstract: The protective efficiency of a number of nitrogen containing inhibitors against steel hydrosulfide corrosion and their effect on the kinetics of partial electrode reactions have been studied by gravimetrical corrosion tests, polarization resistance and impedance spectroscopy methods. The bactericidal efficiency of the inhibitors with respect to sulfate reducing bacteria (SRB) has been estimated as a function of their nature and concentration.

Keywords: inhibition, corrosion, protective effect, polarization resistance, impedance spectroscopy, bactericidal action
