摘要
介绍了在提高镀涂层耐蚀性方面的两项成果:一是在镁中加入少量能毒化其阴极腐蚀反应的砷,二是在材料表面构造微-纳米粗糙结构及修饰一层疏水性极强的自组装膜(如硅烷偶联剂、巯基化合物和长链有机羧酸)。综述了通过电沉积、化学沉积、气相化学沉积、蚀刻、涂装等方法来得到超疏水表面的研究进展。指出了这两项领域未来的研究方向。
Two breakthroughs in improving the corrosion resistance of coatings were introduced:the first is the poisoning of cathodic corrosion process of magnesium by addition of arsenic,and the second is the fabrication of micro-/nanometer structure on the surface of material covered with a highly hydrophobic self-assembled membrane of silane coupling agent,mercapto compound,long-chain carboxylic acid,and so on.The methods for preparation of superhydrophobic surfaces such as electrodeposition,chemical deposition,vapor chemical deposition,etching,and painting were reviewed.The research directions of these technologies in future were pointed out.
