| Abstract: | In this paper,the property variations of inorganic and organic zinc-rich coatings were studied with electrochemical impedance spectroscopy.The surface morphology of the coatings and the compositions of corrosion products before and after immersed were studied with SEM and EDAX respectively.The failure mechanism of inorganic and organic zinc-rich coatings in 3.5% NaCl solution were analysed and discussed using these three methods. |
