摘要：The effect of silicon and phosphorus content in steel suitable for galvanizing on its corrosion inhibition in 5 M hydrochloric acid solution in absence and presence of 100 ppm of Cetyltrimethylammonium combined with 100 mM of KI (mixture) was studied with conventional corrosion monitoring techniques. This study was carried out by using weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) measurements. Potentiodynamic polarization measurements showed that the mixture acted as mixed type inhibitor for the three classes. The experimental results have showed that this organic compound revealed a good corrosion inhibition of steels classes A and B than class C. Thus, the inhibition efficiency was about 97 %, 92 % and 76 % for three classes A, B and C respectively. This founding indicated that the corrosion inhibition depended of the steels composition according to their silicon and phosphorus contents
