Studying and comparing the erosion-enhanced pitting corrosion of X52 and X100 steels

open access: yesInternational Journal of Electrochemical Science, 2012
The critical ratio of Cl− to HCO− concerning the corrosion rate has been determined with and without electrolyte erosion in 0.3 M NaHCO3 by using various concentrations of NaCl for X52 and X100 steels.
