Superhydrophobic Surface On Aluminum Alloy By Hydrothermal Method And Its Electrochemical Performance, Xiao-Hang Chen, Mo-Jing Chen, Yu-Lin Min, Qun-Jie Xu

Journal of Electrochemistry

Superhydrophobic film formed on a metal surface is an effective way for corrosion protection. In this paper, the superhydrophobic film was prepared on the surfaces of aluminum alloy by hydrothermally treating with a solution containing CeCl3·7H2O and CO(NH2)2 , and a self-assemble process. The electrochemical measurements and surface morphology results confirmed that the best superhydrophobicity and electrochemical performance could be achieved with the contact angle of 155.5o after six hours of hydrothermal reaction. Furthermore, the inhibition efficiency of 99.6% was obtained in 3.5 wt% NaCl aqueous solution, indicating the excellent corrosion resistance …

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%.
