Special Issue Information

Dear Colleagues,

This Special Issue of Applied Sciences is dedicated to the latest research and review articles on electrochemistry and the corrosion of metallic materials. Corrosion causes significant economic damage globally across the transportation, energy, utility and infrastructure sectors, with costs estimated to be in USD trillions annually. By effectively investigating corrosion, we can enhance our understanding of corrosion mechanisms, enabling the scientific community to develop suitable structures, microstructures, coatings and other solutions to mitigate corrosion. Electrochemical methods allow us to measure corrosion at various length scales, from microscopic to macroscopic levels. Additionally, combining electrochemical data across these scales with multiphysics modeling can improve the accuracy of corrosion kinetics predictions and aid in designing corrosion-resistant structural and functional materials.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Acid pickling is a vital stage in metal manufacturing during which the material is susceptible to corrosion if the process is not appropriately managed. Adding green corrosion inhibitors to the acidic solution used is one solution to this critical problem that the industry faces today. This paper examines the application of two organic substances, tea tree essential oil and the expired drug Sinecod, as green corrosion inhibitors for carbon steel in concentrated chlorohydric acid. Corrosion behavior is evaluated using the weight loss method, potentiodynamic polarization, and electrochemical impedance spectroscopy for three inhibitor concentrations (1%, 2%, 3%, and 4%) and a Blank sample. SEM analysis was performed for surface analysis. The mechanism of inhibition was also investigated by fitting the electrochemical data to adsorption isotherms such as the Langmuir and the Freundlich models. The optimum concentration proved to be 4% for both substances, with inhibition efficiencies up to 90% in the case of tea tree essential oil and up to 60% in the case of expired Sinecod, showing that the inhibitor concentration and inhibitor efficiency are directly correlated in this case. The findings of this study show the possibility of using expired pharmaceutical compounds or natural extracts as corrosion inhibitors for the concentration of acid solutions used for industrial processing.
