This paper investigates, using surface characterisation techniques (SEM, XPS and ToF-SIMS), the impact of marine biological activity on AA5083 corrosion behaviour during seawater immersion. Different solar exposure (light vs. dark) results in distinct fouling development, influencing modifications. On dark side, an Al/Mg oxide/hydroxide layer forms, allowing Cl- penetration. Pitting attack is observed after For light a dual structure with hydrated Mg rich outer layer, showing barrier effect...
This study provides a detailed characterization of the AA5083 aluminum alloy, surface, and interface over 6 months immersion in seawater, employing techniques such as SEM/EDX, GIXRD, μ-Raman XPS. The purpose was to evaluate evolution biomineralization process that occurs on Al–Mg alloy. By investigating specific conditions favor situ growth layered double hydroxide (LDH) during seawater result biomineralization, this research insights into marine highlighting its potential an innovative...
This study investigates the formation of a protective layer on 5083 aluminum alloy surface induced by microorganisms from salt marsh. The influence initial roughness was examined to identify optimal conditions for maximum coverage and thickness layer. As two opposing effects are suspected, where high enhances bacterial adhesion but reduces resistance abiotic corrosion, various degrees were tested. Using electrochemical experiments (OCP measurement, 1/Rp determination, pitting sensitivity),...
Microbial electrolysis cells (MEC) must work around neutral pH because of microbial catalysis at the anode. To develop a hydrogen evolution cathode that can remains major challenge in MEC technology. Voltammetry performed 8.0 on rotating disk electrodes showed presence phosphate species straightforwardly multiplied current density evolution, through so-called cathodic deprotonation reaction. The mechanism was stable stainless steel cathodes whereas it rapidly vanished platinum....
This study aimed to investigate the influence of galvanized steel coupons on black tea kombucha fermentation. As a secondary objective, corrosion activity fermented medium at different stages fermentation was investigated. The results revealed significant interactions among microorganisms, metal, and medium. On one hand, mass loss measurement, scanning electron microscopy (SEM) analysis, released zinc iron ion analysis showed deterioration coupons. other HPLC-RI that presence improved...
