“…However, the OCP variation of 0.3 wt %-RGZ composite coating exhibits an almost stabilized potential response in the initial stage and then a slight increase toward the end of monitoring. This stable OCP variation tendency of 0.3 wt %-RGZ composite coating in all the bacterial suspensions indicates its ability to inhibit the biofilm growth and electrochemical stability even after long-term exposure. , …”

This paper reports the development of multifunctional rGO–ZnO composite (RGZ) coatings with enhanced mechanical, anticorrosion, and antibacterial characteristics for practical marine applications. The structure and composition of the RGZ composite coatings are tuned to achieve distinct and compact intermetallic alloy layers, leading to improved hardness, wear resistance, friction resistance, electrochemical stability, and antibacterial activity. 0.3 wt %-RGZ composite coating with the highest R ct value (367.8 Ω cm2) exhibits the least corrosion rate (0.75 mmpy) as compared to the other compositions of the developed coatings. All the RGZ composite coatings exhibit enhanced antibacterial activity in different bacterial suspensions selected for the present study (Escherichia coli, Bacillus subtilis, and seawater consortium), and the 0.3 wt %-RGZ composite coating is demonstrated to be suitable for marine applications with the lowest bacterial survivability (20.3%) in the seawater consortium. The electrochemical stability and anticorrosion performance of the 0.3 wt %-RGZ composite coating even after long-term exposure (28 days) to seawater consortium confirmed from the largest R ct value (1154.7 Ω cm2) and the least i corr value (223.4 μA/cm2) indicate its suitability for practical application with excellent reusability. The enhanced antibacterial activity of the 0.3 wt %-RGZ composite coating as compared to other compositions of RGZ coatings and bare-Zn coating is attributed to its three-level bacterial destruction capability by inducing damage to the bacterial cell wall through physical damage, penetration of Zn2+ ions, and the activity of the photogenerated reactive oxygen species (ROS). The enhanced antibacterial activity and excellent electrochemical stability with attractive anticorrosion performance of 0.3 wt %-RGZ composite coating even after long-term exposure (28 days) in different bacterial suspensions, especially in seawater consortium, confirm its suitability for practical applications.

“…In the actual marine environment, the mechanism of microbial corrosion inhibition is more complex than traditional strategies. The main mechanisms of microbiologically influenced corrosion inhibition (MICI) comprise corrosion inhibitor secretion, biofilm, corrosion product shielding effects, alterations in the local micro-environment, and modifications in anodic and cathodic processes [ 127 ].…”

Microbially influenced corrosion (MIC) is a formidable challenge in the marine industry, resulting from intricate interactions among various biochemical reactions and microbial species. Many preventions used to mitigate biocorrosion fail due to ignorance of the MIC mechanisms. This review provides a summary of the current research on microbial corrosion in marine environments, including corrosive microbes and biocorrosion mechanisms. We also summarized current strategies for inhibiting MIC and proposed future research directions for MIC mechanisms and prevention. This review aims to comprehensively understand marine microbial corrosion and contribute to novel strategy developments for biocorrosion control in marine environments.

“…(Qu et al, 2015;Guo et al, 2021;Gao et al, 2022). The inhibition mechanism includes the shielding effect of biofilm and corrosion products, inhibition of the secretion of corrosive substances, and alteration of the local microenvironment (Wang et al, 2022). The widespread use of chemical fungicides to control the harm caused by microbial corrosion, although a certain effect, but the long-term use of fungicides will make the bacteria resistant, and at the same time will bring pollution to the environment (Enning et al, 2016).…”

In this paper, the effect of Alcaligenes sp. on the corrosion process of X65 steel was investigated by using non-targeted metabolomics techniques for comprehensive characterization of metabolites, combined with surface analysis techniques and electrochemical testing. The results showed that the organic acids produced by Alcaligenes sp. accelerated the corrosion process of X65 steel in the early stage, and the presence of Alcaligenes sp. promoted the deposition of stable corrosion products and minerals in the middle and late stages. In addition, proteoglycans and corrosion inhibiting substances were enriched on the metal surface, which enhanced the stability of the film. The combined effect of multiple factors makes the mixed film of biofilm and corrosion products more dense and complete, which effectively inhibits the corrosion of X65 steel.
