摘要：

Weight loss method, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) were used to study the synergistic inhibition effect of sodium dietyldithiocarbamate (DDTC) and hexadecyltrimethylammonium bromide (CTAB) for the corrosion of cold rolled steel (CRS) in 0.05 M acetic acid (HAc) solution. It is observed that the combination between DDTC and CTAB is physically adsorbed on the surface of CRS, thus showing excellent inhibition efficiency. In this article, the Hard-Soft Acid-Base (HSAB) principle has used to explain the mechanisms of Synergistic inhibition between DDTC and CTAB. SEM and FT-IR results further validate the corrosion inhibition mechanism we proposed.
