摘要

The corrosion behavior of Zn-Al-Mg-RE sealed and unsealed coatings fabricated by high-velocity arc spraying on Q235 steel was studied in seawater with sulfate-reducing bacteria (SRB) using electrochemical impedance spectroscopy(EIS), polarization curve(PC), scanning electron microscopy (SEM) and energy dispersive spectroscopy(EDS). The results show that the corrosion rate of unsealed and sealed Zn-Al-Mg-RE coatings first increases and then decreases; the corrosion resistance of Zn-Al-Mg-RE coating apparently improves by the sealing treatment. After immersion, the two coatings surface is covered by a passivation film layer of microorganism and corrosion products, which avoids the coating from being further damaged.
