采用硬-软技术在铝合金上制备了耐用的超疏水涂层，包括在硬质阳极氧化铝纳米通道中原位电化学生长TiO2纳米颗粒以及十八烷基三甲氧基硅烷的改性。改性后的分级微观结构赋予涂层优异的疏水性，热处理后即使表面进行大面积抛光，涂层的疏水性能也能恢复，从而显着提高了超疏水涂层的耐腐蚀性能。硬软技术增强了超疏水涂层的耐久性，为硬质涂层的腐蚀防护提供了新策略。
A durable superhydrophobic coating on aluminum alloy is fabricated by the hard-soft technology, including in-situ electrochemical growth of TiO2nanoparticles in the nanochannels of hard anodic aluminum oxide and modification of octadecyl trimethoxysilane. The modified hierarchical microstructure endows the coating with the excellent hydrophobicity, and the hydrophobic property of the coating can be recovered after heat treatment even though the surface is extensively polished, thus, the corrosion resistance of the superhydrophobic coating is significantly improved. The hard-soft technology strengthens the durability of the superhydrophobic coating, and provides a new strategy for the corrosion protection of hard coating.
