Corrosion behavior of low carbon steel processed by ECAP in neutral and alkaline environment

The purpose of this study was to evaluate the corrosion behavior 1010 steel processed by Equal Channel Angular Pressing (ECAP), a technique that induces severe plastic deformation (SPD) in materials. samples were one and two passes ECAP throught routes A C. using potentiodynamic polarization electrochemical impedance spectroscopy, NaCl (pH= 6.5) sodium hydroxide/sodium phosphate 10.5) solutions. tests showed better performance for than as cast both alkaline neutral results solution presented higher rate pass It is seen C develop film stabilization on surface these samples. In addition, values resistance obtained from spectroscopy environment sample route
