Abstract

The paper presents the electrochemical corrosion behavior of carbon steel X60 using the electrochemical impedance spectroscopy and potentiodynamic polarization methods. As test solutions sodium chloride, sodium sulphate and sulphuric acid 0.5M concentration were used in a three electrode open cell. It was observed that the corrosion rate (corrosion current) is higher for carbon steel X60 in 0.5M sulphuric acid and smaller in 0.5M sodium sulphate..
