“…Additionally, goethite (αFeOOH) is detected at the Vert-Pré site. These corrosion products have been previously identified in analogous marine environments [33][34][35]. The absence of chlorinated products is likely attributed to their solubility, unlike the stable basic salts observed with other metals.…”

This article aims to investigate the atmospheric corrosion of carbon steel in a marine environment abundant in hydrogen sulfide (H2S) resulting from the decomposition of Sargassum seaweed. To accomplish this, four sites with varying degrees of impact were chosen along the coast of Martinique. The corrosion rates of steel were evaluated through mass loss measurements. After one year of exposure, the corrosion rates were notably high, particularly in atmospheres rich in Cl− ions and H2S, ranging from 107 µm to 983 µm. Complementing these findings, surface and product morphologies were characterized using scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). These analyses revealed a significant degradation of the corrosion surface in the most affected atmospheres compared to those unaffected by Sargassum seaweed strandings. Lepidocrocite (γFeOOH) was identified as the predominant product regardless of the exposure atmosphere. However, goethite (αFeOOH) was found to be present in atmospheres most impacted by H2S.

“…Additionally, goethite (αFeOOH) is detected at the Vert-Pré site. These corrosion products In Diamant and Vert-Pré, the observed surface morphologies typically resemble those commonly found in a marine atmosphere [33][34][35]. The evolution of the corrosion surface at these two sites is relatively similar.…”
