| Abstract: | A comparative study about the corrosion behavior of Al-Zn-In-Mg-Ti sacrificial anode in marine sediment without and with sulphate reducing bacteria(SRB) was carried out using electrochemical impedance spectroscopy(EIS),scanning electron microscopy(SEM) and energy dispersive spectroscopy(EDS).The electrochemical studies showed that the corrosion potential for samples exposed to sterile marine sediment was higher than that for samples exposed to the SRB-containing marine sediment during the whole experiment;the corrosion of the sample was enhanced sharply in the presence of SRB.SEM images revealed that the presence of localized corrosion morphologies on the surface of sample immersed in the sterile medium as well as in the biotic medium,but the damage in the biotic medium was more severe than that in the sterile medium.EDS analysis showed that the concentration of Al and Zn in the surface film for the sample with SRB was much lower than that for the sample without SRB. |
