| Abstract |
The microbiological influenced corrosion (MIC) behaviors of the ship plate steel directly
exposed in different medias (the sterile seawater, the ferrous bacteria solution and the
sulfate-reducing bacteria solution) were investigated with electrochemical impedance spectroscopy
(EIS), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and scanning electron
microscopy (SEM). Corrosion potential, electrochemical impedance and micrographs of specimens
under different experimental conditions were obtained. Results show that the FB and SRB in the
marine environment affect the corrosion behavior of the ship plate steel greatly. The corrosion
process in FB and SRB environment was controlled by both bacteria and corrosion products. The
mechanism of MIC is discussed. |
