Special Issue Information

Dear Colleagues,

Metals and alloys used in marine environments face significant challenges due to corrosion caused by the seawater, humidity, temperature variations, and biological activity found in these harsh environments. The presence of chloride ions in seawater accelerates corrosion, leading to material degradation, structural failures, and substantial maintenance costs. The long-term durability of metallic structures in marine environments is a critical concern, especially for industries such as shipbuilding, offshore energy, and underwater infrastructure.

This Special Issue aims to explore recent advancements in our understanding of corrosion in order to prevent and mitigate marine corrosion in metals. It will cover the fundamental mechanisms of marine corrosion, including uniform corrosion, pitting corrosion, crevice corrosion, galvanic corrosion, and microbiologically influenced corrosion (MIC). A comprehensive understanding of these degradation processes is essential for developing effective protection strategies.

Additionally, this Special Issue will highlight innovative corrosion protection techniques such as advanced coatings, cathodic protection, corrosion inhibitors, and the design of corrosion-resistant alloys. The development of eco-friendly and sustainable corrosion inhibitors is of particular interest, given the growing need for environmentally responsible solutions. Furthermore, the use of emerging technologies in corrosion monitoring, predictive modeling, and electrochemical analysis will be explored to improve real-time assessments and long-term corrosion control.

By gathering high-quality research and review articles, this Special Issue seeks to contribute to the development of durable and sustainable materials for marine applications. The findings presented will have direct implications for industries that rely on marine infrastructure, including naval engineering, offshore oil and gas platforms, pipelines, and renewable energy structures such as offshore wind farms.

We invite researchers and industry professionals to share their latest findings and technological innovations in the realm of marine corrosion science and engineering. We look forward to your valuable contributions to this Special Issue.

Cathodic protection (CP) is used in the marine industry to prevent corrosion of metal components in seawater but may also promote biofilm formation. When steel and copper alloy components are in contact, the latter is often subjected to higher applied CP voltages than otherwise required when a steel component is not present. In this study, the protection that CP offers in bronze alloys (RG-10 and CC492K) was assessed, both in controlled laboratory conditions and in real marine conditions in the Bay of Biscay (up to 3000 h), with various temperatures and methods: sacrificial anodes and impressed currents under different voltages. After the exposures, visual, scanning electron microscopy (SEM), X-ray diffraction (XRD) and corrosion rate analyses were performed. The results showed faster biofouling deposition on surfaces with a higher CP voltage, exposed to marine seawater, at the early stages. Subsequently, for longer exposure times, intermediate CP voltages offered less biofouling protection. XRD analyses showed the presence of calcareous compounds (calcite and aragonite), among others. Meanwhile, the corrosion observed in the laboratory was mediated by the amounts of deposited salts, with higher corrosion corresponding to higher CP voltages. Changes in temperature for the same CP voltage caused quantitative and qualitative differences in salt deposition. The higher Pb content of the CC492K alloy compared with the higher Cu and Sn contents of GR-10 did not manifest at the biofouling level, but different corrosion rates were measured (GR-10 < CC492K). Thus, the optimal CP protection conditions for marine and laboratory environments are not the same, because of the different conditions involved. Full article
