中文摘要: |
采用浸泡法,在含水量不同的十四烷基硫醇 / 乙醇-水溶液中,使 2024 铝合金表面自组装烷基硫醇膜,通过动电位扫描、电化学交流阻抗、原子力显微镜以及光电子能谱研究了硫醇自组装膜在铝合金表面的吸附行为及缓蚀性能。 结果表明,十四烷基硫醇自组装膜对铝合金在 Harrison 溶液中的腐蚀具有一定缓蚀作用,且缓蚀效果随着自组装溶液中含水量的增加而增强。 |
英文摘要: |
Self-assembled monolayers ( SAMs) of 1-Tetradecanethiol ( TDT) were prepared on the surfaces of 2024 aluminum alloys by immersing method in the TDT solutions using mixtures of absolute ethanol and water with different volume ratios as the solvents. The adsorption behavior and corrosion inhibition performance of TDT SAMs were investigated by potentiodynamic scanning, EIS ( electrochemical impedance spectrum) , AFM ( atomic force microscopy ) and XPS ( x-ray photoelectron spectroscopy) . The results indicate that TDT shows a certain inhibition effect on the corrosion of aluminum alloys in Harrison solution,and the inhibition efficiency increases with the increasing of water content in the assembly solution. |
