| The biofilm developing on carbon steel surfaces in anaerobic condition may induce localised corrosion. To be able to better understand this type of biocorrosion, this paper presents a new electrochemical technique, which has been developed in collaboration between IFREMER and the Laboratory for liquid physic and electrochemistry. Focussed on local aspect of this phenomenon, the described technique enables surface current density mapping to be performed and anodic or cathodic zones to be identified. A double microelectrode probe is placed closed to the steel sample surface and potential difference between them is measured. This value is directly connected to ohmic drop within electrolyte and consequently, to local current. By scanning the substrate surface,... |
