摘要：

The effect of two cationic surfactants, cetyl-trimethyl ammonium chloride (CTAC) and cetyl-dimethyl-hydroxyethyl ammonium chloride (CDHAC), on the corrosion of mild steel in HCl solution was investigated by using weight loss measurements. The corrosion inhibition efficiency of CDHAC was higher than that of CTAC in any case. And the activation energies of CTAC and CDHAC involved in the corrosion inhibition were calculated and discussed by the relationship of corrosion rate (W-corr) and temperature (T) from Arrhenius equation. Most importantly, it was found that the structure-efficiency of these two compounds was associated with these adsorption isotherm and thermodynamics.
