Special Issue Information

Dear Colleagues,

Corrosion remains a major challenge in sustainable industrial development, particularly as the world transitions toward greener energy and circular economy principles. Metals and alloys play a crucial role in renewable energy systems, hydrogen infrastructure, carbon capture technologies, and material recycling, but their long-term durability is often compromised by complex corrosion mechanisms. Understanding and mitigating corrosion in these environments is essential to improve efficiency, reduce environmental impact, and ensure the longevity of critical infrastructure.

This Special Issue, entitled "Corrosion and Sustainability: Challenges, Innovations and Future Perspectives in Green Energy", aims to collate the latest research on corrosion-related challenges and solutions in sustainable technologies. Topics of interest include, but are not limited to, the following:

  • Hydrogen embrittlement and corrosion in hydrogen production, storage, and transport;
  • Eco-friendly corrosion inhibitors and sustainable protective coatings;
  • Corrosion of materials in carbon capture, utilization, and storage technologies;
  • Corrosion challenges in emerging energy technologies from lithium batteries to hydrogen infrastructure;
  • The impact of corrosion on recycled metals and circular economy strategies.

We invite researchers from academia and industry to contribute original research articles, reviews, and case studies that explore cutting-edge corrosion science and sustainable engineering solutions.

We look forward to receiving your valuable contributions.

The corrosion behavior of Inconel 718 alloy, developed through two different methods—forging (S1) and additive manufacturing (S2)—was evaluated in a seawater environment, and the results were compared with those of Inconel 825 alloy (S3). The corrosion performance of the alloys was examined according to ISO 8044/2024, using open circuit potential (OCP), potentiodynamic polarization (PP), and electrochemical impedance spectroscopy (EIS), in natural seawater at 25 °C over an extended immersion period. After 5000 h of immersion, the corrosion rate (Rcorr) estimated from anodic polarization tests was found to be lower for the wrought Inconel 718 alloy (1.21 µm y−1) compared to the wrought 825 alloy (4.1 µm y−1) and to the SLM Inconel 718 alloy (35.1 µm y−1), indicating high corrosion resistance for wrought Inconel 718. A morphological analysis of the alloy’s surface conducted using scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy (EDS) revealed a continuous, compact film with localized salt deposits on wrought Inconel 718 and Incoloy 825. In contrast, SLM Inconel 718 exhibited a porous, inhomogeneous film, leading to reduced protective capabilities and lower corrosion resistance. The results demonstrate that wrought Inconel 718 exhibits excellent corrosion resistance in seawater, making it a promising alloy for marine applications. Full article

This study develops an artificial neural network (ANN) model to predict the corrosion rate of carbon steel under a wide range of atmospheric conditions. The model incorporates input variables, including temperature (−3.1–28.2 °C), relative humidity (33.3–91.1%), time of wetness (0.003–0.976), precipitation (13–4656 mm), sulfur dioxide (0–68.2 mg/m2·d), and chloride concentrations (0 to 359.8 mg/m2·d). The model demonstrated excellent predictive capability and reliability, with R2 values of 97.2% and 77.6% for the training and testing datasets, respectively. The model demonstrated a strong predictive performance, with an R2 of 97.2% for the training set and 77.6% for the test set. It achieved a mean absolute error (MAE) of 5.633 μm/year for training and 18.86 μm/year for testing, along with a root mean square error (RMSE) of 0.000055, indicating reliable generalization despite the limited dataset size. The analysis showed that the relative humidity had the most significant impact on the corrosion rate. The practical applications of the model extend to optimizing material selection and devising effective maintenance strategies. Full article

A novel tera-dentate salen ligand and its Fe(III) complex was synthesized and characterized via several spectroscopic and physicochemical techniques. The corrosion rate inhibition of nickel and its alloys inspired the utilization of the L ligand and its FeL complex as vital and eco-friendly inhibitors. To assess their effectiveness, both Tafel plot analysis and electrochemical impedance spectroscopy were employed to examine the electrochemical properties of L and the FeL complex. The results show that corrosion current density (Icorr) steadily drops when the additive concentration is increased, but the inhibition efficiency increases. It has been observed that the efficiency of inhibition rises with temperature, particularly at high temperatures (55 °C) when 1 × 10−3 M of L and FeL are present as additives, with η = 90.5% and 92.7%, respectively. Additionally, the findings propose that the adsorption mechanism of both L and FeL additive reptiles follows the Langmuir design isotherm. Electrochemical impedance spectroscopy has also verified these findings. DFT calculations were employed to prove the structure of the investigated FeL complex and its activity as a corrosion inhibitor. Full article
