Titre : Biofilm, biocorrosion and ALWC study in French port environment through in situ tests

Abstract : Microbiologically Influenced Corrosion (MIC) of carbon steel construction is widely observed in port environment in tidal and immersion zone. In the case of low water zone of microorganisms in the Accelerated Low Water Corrosion (ALWC) phenomena the influence has been identified. Most French laboratories, industrials and ports cooperate in research programs to study the bacterial consortia of marine biofilm on carbon steel surface. This study is conducted in laboratory for the fundamental approaches, but the applied approach is conducted through in situ tests in port environment in Atlantic Ocean, English Channel and Mediterranean Sea. This experimental system is developed for investigations in tidal and low water zone, with and without cathodic protection (permanent, after pre-colonization, with failure simulation). The research objectives are: to develop analytic methods, to estimate the most dangerous biofilm consortia, to estimate some risk factors for corrosive metabolism, and to estimate a prevention plan for port authorities.

Titre : Thin layers of iron corrosion products electrochemically deposited on inert substrates: synthesis and behaviour
Année : 2004
Auteur(s) : Peulon S. Antony H. Legrand L. Chaussé A.
Abstract : The deterioration of iron-based materials due to corrosion is a well-known problem. A variety of corrosion products can be formed depending on the species present in the medium (soil, water, etc.). Understanding the transformation pathways during the evolution of a corrosion layer is a hard challenge since it is difficult to clearly identify the contributions of each corrosion product. That is why the development of electrodes with only one iron corrosion product deposited as thin layers on inert substrates (gold, silver) presents many advantages to carry out electrochemical studies. In this way, the present paper reports successful electrochemical synthesis of thin layers deposited on inert substrates (gold, silver) of commonly occurring iron corrosion products as siderite, green rusts incorporating carbonate or sulphate anions, magnetite and goethite. The films are characterised by usual ex-situ techniques: FTIR, SEM, and XRD. The study of the electrochemical behaviour of thin films of green rust deposited on silver illustrates the potential application of such electrodes.

Abstract : Lepidocrocite thin films have been electrochemically synthesised on polycrystalline Au substrates following two ways, direct synthesis and synthesis via green rust (GR). The direct synthesis consists in oxidising Fe(II) species in a 0.4 M NaCl/0.02 M Met-Imidazole/0.01 M FeCl2 solution at pH 7.5. The synthesis via GR consists in converting a green rust thin film into lepidocrocite thin film by galvanostatic oxidation. The thin films have been characterised by means of electrochemical quartz crystal microbalance, scanning electron microscopy, X-ray diffraction and infrared reflection–absorption spectroscopy.
