Green Inhibitors for Metals Corrosion: Electrochemical Investigations

Dear Colleagues,

It is recognized that pure metals and metallic alloys are intensively susceptible to corrosion. This means a degradation phenomenon, where, in particular point of view, the metals are subjected to an electrochemical condition. This is caused by the potential difference between the anode (which can be a phase of a metallic material) and the cathode (another phase or intermetallic compound). In order to decrease corrosion effects, inhibitor contents are added to the corrosive medium. These compounds are adsorbed onto the metal surface, and corrosive effects can thus be minimized. The majority of inhibitors contain contaminants and harmful particles. Based on this, a new class of corrosion inhibitors, designated as green inhibitors, is emerging, with particular focus being paid to their biodegradability, low toxicity, availability, and environmental friendliness. In this Special Issue, a wide set of manuscripts and investigations focusing on the above-mentioned aspects will be included. Thus, investigations involving metals and metallic alloys and compounds, by using electrochemical impedance spectroscopy and potentiodynamic polarization techniques, are expected to characterize corrosion inhibitor behavior. Distinctive and modified media and materials are characterized and evaluated. Therefore, researchers are invited to propose original investigations, involving a wide range of materials that demonstrate the effects and characteristics of green inhibitors.

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. Metals is an international peer-reviewed open access monthly 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 2600 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.
