    New trends in research of highly corrosion-resistant coatings // FANG Jing-li

    Abstract: 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.

    Keywords: coating; corrosion protection; cathodic poison; superhydrophobic surface; micro-/nanometer rough structure;
