The anti-corrosion performances of single(TEOS) and hybrid (APTES-TEOS) sol-gel coatings on Al alloy samples exposed to 3.5 wt% NaCl were evaluated employing electrochemical techniques such as electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization. The data acquired using the three corrosion analysis techniques were in accordance with each other where hybrid sol-gel coating offered the lowest corrosion rate and current density in comparison to the single precursor silanol coating. Tafel curves suggested that the hybrid silane coatings mitigate both the anodic and cathodic reactions simultaneously (mixed type inhibitor). These techniques justified that incorporation of hybrid sol-gel improved the Al corrosion protection performance considerably.
采用电化学阻抗谱（EIS）和动电位极化等电化学技术，评估了暴露于3.5 wt% NaCl中的铝合金样品上的单一（TEOS）和混合（APTES-TEOS）溶胶-凝胶涂层的防腐性能。使用这三种腐蚀分析技术获得的数据相互一致，与单一前驱体硅醇涂层相比，混合溶胶-凝胶涂层的腐蚀速率和电流密度最低。塔菲尔曲线表明，混合硅烷涂层同时减轻了阳极和阴极反应（混合型抑制剂）。这些技术证明，混合溶胶-凝胶的加入显著提高了铝的腐蚀防护性能。
