N2 - This chapter presents a study on the determination and characterization of corrosion of ferrite and pearlite on a steel sample, in the borate medium, by using an in-situ Electrochemical Scanning Tunneling Microscopy (ECSTM). The real time monitoring of changes in the steel surface topography, allows to understand each phase oxidation as well as their influence on the global carbon steel corrosion process. The use of ECSTM successfully characterized the state of the electrode surface, identified phases at the steel sample, and determined the surface morphology characteristics; and the systematic monitoring of topography change enabled to determinate and differentiate oxidation mechanisms of different steel phases (pearlite vs. ferrite). Real time images were obtained during the immersion of 1018 carbon steel probes in 0.642 M H3BO3 and 0.1 M NaOH, pH = 7.8. Two different corrosion mechanisms were identified and correlated with the observed surface changes.
