摘要/Abstract

摘要：

在金属表面构建超疏水膜层是一种有效的防腐技术，本文采用水热处理和自组装技术在铝合金表面构建了超疏水膜层来提升铝合金的耐蚀性能. 通过对不同水热时间下制备的铝合金超疏水表面的电化学性能以及表面形貌进行测试分析，发现当水热反应时间为6 h时，制备的超疏水铝合金超疏水性和电化学性能达到最佳，接触角能达到155.5^o，在模拟海水溶液中保护效率能达到99.6%.

Abstract:

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 155.5^o 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 of superhydrophobic film.

Key words: superhydrophobic, aluminum, electrochemistry, corrosion inhibition, hydrothermal method
