Special Issue Information

Dear Colleagues,

Marine engineering equipment is a "heavy weapon" in the process of cognizing, exploiting, utilizing, and protecting the ocean, as well as the "backbone" supporting various ocean-related endeavors such as ocean scientific research, resource development, and safety assurance. However, seawater is a good conductor of electricity, high in salt and oxygen, which leads to a very high corrosion rate of metal-based marine engineering equipment and facilities. At the same time, low-frequency alternating stress and the impact force generated by waves, currents, and tides, as well as marine organisms and their metabolic products, all have a direct or indirect accelerating effect on the corrosion damage process. High-performance protective materials are key to ensuring the manufacturing, development, and long-term high-reliability operation of high-end marine engineering equipment.

This special Issue aims to provide an overview of the latest innovations related to metal corrosion and protective materials in the marine environment. This Special Issue focuses on experimental, numerical, and analytical studies on the metal corrosion mechanism, advanced corrosion resistance materials, and their applications.

The Ni-Au coating with its inherent chemical stability is recognized as an effective method for boosting corrosion resistance in humid environments while preserving exceptional electrical conductivity. However, its anti-corrosion performance is affected by the structure characteristics of the coating due to the high corrosion potentials of Au and Ni. To enhance its protection properties, the deposition process parameters, including deposition time, deposition current density, and zincating times, were investigated. The morphology and structure of the coatings were characterized, while its anti-corrosion performance was assessed through electrochemical and accelerated salt-spray tests. Eventually, the elevated current density in the Ni-Au coating resulted in reduced grain size and improved surface morphology, ensuring superior anti-corrosion performance. Additionally, extending the Ni deposition time provided a second physical barrier for the dense and thick Ni layer to resist the invasion of corrosive media. Furthermore, grey theory was applied to predict the service life of the Ni-Au coating. This research provides valuable insights and constructive guidance for optimizing Ni-Au coating in various engineering applications. Full article
