Corrosion Inhibition Of Self-Assembled Films On Iron By Electrochemical Impedance Spectroscopy, Yuan-Yuan Feng, Shen-Hao Chen, Juan-Juan Zhou, Wen-Juan Guo
Journal of Electrochemistry
The self-assembled films of tetradecylamine were formed on iron surface,and the inhibition ability of which for iron corrosion in 0.5 mol/L H2SO4 solutions was studied by electrochemical impedance spectroscopy technique.Results indicated that longer immersion time would result in stronger inhibition ability of the films.The maximal inhibition efficiency(IE) of the tetradecylamine films was 68.7%.When the tetradecylamine films were modified by dodecylthiol,the mixed films became denser and more stable,thus the inhibition ability increased remarkably.The η of the mixed films increased to 78.2%.
