Abstract
The corrosion resistance of Lord Razor Blade Steel (LRBS) specimens made of low carbon steel has been compared in aqueous borate (pH 9.0), 1.0 M NaOH and 0.5 M NaCl solutions at 25°C. The investigation was accomplished utilizing potentiodynamic polarization curves (PPC’s), cyclic potentiodynamic polarization (CPP), electrochemical impedance spectroscopy (EIS), open circuit potential (OCP) and chronoamperometric (j-t transients) techniques, complemented by SEM study. The study was also carried out on mild steel (MS) for comparison. It was found that the corrosion resistance of LRBS specimens in the borate solution is higher than that in NaCl and NaOH solutions. Moreover, the LRBS specimens possess a higher corrosion resistance than the MS in the same tested solutions.
