| 中文摘要 | Microbiologically influenced corrosion is a serious problem for stainless steels in marine engineering. In this study, the attachment of a typical biofouling microalgae Chlorella vulgaris on the surface of 316L stainless steel was determined by a light microscopy. Its influence on the electrochemical behavior of this material was also evaluated by electrochemical techniques, including open circuit potential, electrochemical impedance spectroscopy and polarization curves. The results showed that this algal species could attach to the surface of 316L stainless steel without any extracellular polymeric substance. This action was not sensitive for the surface roughness but was influenced by the environmental pH value. The adhesion density reached a maximum at pH 9 value. Electrochemical results showed that this algal species had a corrosion inhibit efficiency for 316L stainless steel during a short period of immersion (14 d). This was mostly because of the oxygen produced by the photosynthetic activity of planktonic algae. The sessile algae species couldn't induce any influence on the electrochemical behavior of 316L stainless steel. All these results provide a basic knowledge on the influence of microalgae on the corrosion of stainless steel. This is meaningful for interpreting microbiologically influenced corrosion in situ for further. |
