Special Issue Information

Dear Colleagues,

Electrochemical corrosion critically governs the long-term integrity, durability, and safety of metallic materials used across energy, chemical, marine, transportation, and biomedical industries. With the rapid development of hydrogen energy systems, smart infrastructure, additive manufacturing metals, and high-entropy alloys, understanding corrosion mechanisms under increasingly complex environments (e.g., high-pressure hydrogen, microbial activity, extreme temperatures, and electrochemical–mechanical coupling) has become more urgent and scientifically significant. Recent advancements in in situ electrochemical techniques, micro-/nano-scale characterization, computational modeling, and protective coating design further expand the frontier of corrosion science.

We are pleased to invite you to submit research contributions to this Special Issue, “Recent Progress on Electrochemical Corrosion of Metallic Materials,” which aims to provide a comprehensive collection of cutting-edge studies addressing electrochemical corrosion mechanisms, advanced testing methodologies, protection strategies, and emerging application scenarios. This topic fits squarely within the scope of Coatings, particularly concerning corrosion-resistant coatings, surface/interface behavior, and electrochemical performance of metallic systems.

This Special Issue aims to

  • Highlight recent advances in experimental, theoretical, and computational research on the electrochemical corrosion of metallic materials;
  • Provide a platform for state-of-the-art studies on corrosion behavior under extreme or coupled environments (H₂, MIC, stress, tribo-corrosion, etc.);
  • Promote new developments in corrosion-resistant coatings, inhibitor systems, surface modification technologies, and corrosion monitoring/diagnostic techniques;
  • Strengthen interdisciplinary exchanges among corrosion science, surface engineering, electrochemistry, materials characterization, and mechanical integrity research.

Topics of interest include, but are not limited to, the following:

  • Electrochemical corrosion mechanisms of steels, aluminum alloys, titanium alloys, magnesium alloys, additive-manufactured metals, and high-entropy alloys.
  • Corrosion under coupled fields: hydrogen-assisted corrosion, microbial corrosion (MIC), stress corrosion cracking (SCC), and high-pressure or high-temperature environments.
  • Advanced electrochemical testing methods: in situ/operando electrochemistry, localized electrochemical techniques, EIS, SECM, SKPFM, and hydrogen permeation analysis.
  • Protective coatings and surface treatments for corrosion prevention: conversion coatings, sol–gel coatings, nanoparticle-enhanced coatings, anticorrosion/antibacterial coatings, and smart/self-healing coatings.
  • Modeling and simulation of electrochemical corrosion: multi-scale modeling, electrochemical–mechanical coupling, and machine learning in corrosion prediction.
  • Corrosion monitoring, sensor technologies, and field evaluation.
  • Any other topics related to the electrochemical behavior of metallic materials and corrosion protection.

We invite original research articles, reviews, and short communications.

We look forward to receiving your valuable contributions.

Corrosion of pipelines by flue gas desulfurization (FGD) wastewater compromises the normal operation of the desulfurization tower, and corrosion under high-chloride conditions in particular severely damages the tower’s internal structure. To further elucidate the corrosion mechanism at elevated Cl concentrations, the corrosion behavior of 20 steel exposed to high-chloride FGD wastewater at different Cl concentrations was investigated through weight-loss measurements, electrochemical tests, immersion corrosion experiments, composition analysis, and microscopic morphology characterization. The results revealed that higher Cl concentrations corresponded to lower corrosion rates: the corrosion rate reached 0.1964 mm/y in the absence of Cl, but decreased to 0.1537 mm/y at a Cl concentration of 100,000 mg/L. XPS analysis showed that as the Cl concentration increased, the corrosion film gradually transformed from porous FeOOH into dense Fe3O4. Localized pitting analysis indicated a positive correlation between Cl concentration and pitting susceptibility. At Cl concentrations of 0 and 100,000 mg/L, the corrosion current density decreased from 32.44 μA/cm2 to 6.43 μA/cm2 after 72 h, decreasing by a factor of approximately 5.05. This behavior is attributed to the fact that Cl increases solution conductivity in high-chloride environments, thereby promoting the formation rate of the corrosion film. Additionally, high Cl levels reduce dissolved oxygen in the solution, causing the corrosion film to progressively react and form denser Fe3O4. Nevertheless, the high penetrability of Cl continues to aggravate pitting corrosion of 20 steel. Full article
