- Effect of marine microbial activity in corrosion inhibition of 5083 aluminium alloy [Comunicação oral]Publication . Marques, Maria João; Mercier, Dimitri; Seyeux, Antoine; Zanna, Sandrine; Marcus, Philippe; Basseguy, RegineABSTRACT: Microbiologically influenced corrosion inhibition (MICI), can be considered as a new environmentally friendly strategy for corrosion inhibition. Nevertheless, at present, most of the findings in MICI research are obtained under optimized laboratory conditions, generally involving a single microorganism. To upgrade the knowledge in this research field and increase the potential applications, more studies under real conditions are needed, since environmental complexity and biological diversity coexist in field environments impacting the corrosion process of metal surfaces. In this context, one of the main objectives of the MICOATEC project (“New concept of Microbially Inspired anticorrosion coating technology”) is to understand the microbially induced formation of a protective layer on the Al-Mg surface during exposure in marine field. The present work is part of this study.
- Marine micororganisms’action: a hazard that can turn to corrosion protection [Comunicação oral]Publication . Basseguy, Regine; Marques, Maria João
- Microbial action as an inspiring tool to propose innovative corrosion protection processes [Comunicação oral]Publication . Basseguy, Regine; Marques, Maria JoãoABSTRACT: Among the strategies employed to protect metallic materials, coatings can be considered as one of the most successful and cost-effective alternatives to increase the service lifetime of metallic structures, particularly in industries that are continuously exposed to changing and hard weather conditions such as shipbuilding, automobile, aerospace, marine and oil & gas energy infrastructures. However, towards a more constraining legislation as REACH, the surface treatment & coating Industry is at the forefront in developing innovative and even more sustainable products.
- Nouveau concept de technologie de revêtement anticorrosion inspirée des systèmes microbiens: Projet MICOATEC [Comunicação oral]Publication . Marques, Maria João; Jaume, Julien; Diderot, Anthony; Délia, Marie-Line; Basseguy, RegineRÉSUMÉ: Parmi les stratégies actuellement utilisées pour protéger les matériaux métalliques de la corrosion, et ainsi accroître leur durabilité, les traitements de conversion et les revêtements peuvent être considérés comme les alternatives les plus efficaces et les plus rentables. Ces techniques doivent cependant respecter une réglementation de plus en plus contraignante telle que REACH. Par ailleurs, dans le domaine des interactions micro-organismes/ matériaux conducteurs, il a été mis en évidence que non seulement les micro-organismes peuvent dans certains cas accélérer la corrosion (biocorrosion ou MIC) et dans d’autres l’inhiber protégeant alors le matériau sous-jacent (MIC Inhibition). Dans ce contexte, le projet ANR MICOATEC repose sur le constat que les interactions entre un alliage d’aluminium (AA 5083) et des microorganismes du milieu marin conduisent à la formation d’une couche protectrice contre la corrosion (Figure 1). MICOATEC ambitionne de développer, via une stratégie biomimétique, un nouveau type de procédé pour produire des revêtements anticorrosion.
