综述了近几十年来国内外对大气腐蚀过程中液滴覆盖下腐蚀现象的研究,尤其是近十年来随着研究手段的发展,对液滴覆盖下的腐蚀有了深入的研究。主要的研究手段有体视显微镜,环境扫描显微镜,Kelvin电极,原子力显微镜以及电化学阻抗谱等方法。这些现代研究方法的采用,使大气腐蚀的研究向原位观测和原子尺度方向发展,同时促进了对液滴覆盖下腐蚀机理的深入研究。
The development of research methods for corrosion under droplets during atmospheric corrosion is reviewed.With the revolution of experimental technology,the corrosion under droplet has been investigated deeply. Main measuring techniques include microscopy,environmental scanning electron microscopy(ESEM),Kelvin probe, atom force microscopy(AFM),electrochemical impedance spectroscopy(EIS) and so on.Using these modem measurements,the mechanism research of corrosion under droplets has been promoted.The development trend of droplet corrosion research will be in-situ monitoring technology and atomic scale observation.
