Special Issue Information
Dear Colleagues,
High-entropy alloys (HEAs) have garnered significant research attention in recent years due to their unique compositional complexity and exceptional integrated properties. These alloys exhibit superior corrosion resistance, remarkable wear performance, and stable passivation behavior in aggressive environments, making them ideal candidate materials for critical engineering applications. The synergistic effects of multiple principal elements drive the formation of protective passive films, substantially enhancing alloy durability and service reliability. Furthermore, HEAs offer distinct advantages in sustainable material design, including tailorable compositions for specific service conditions, reduced dependence on scarce strategic elements, and extended service life that minimizes material replacement frequency and environmental footprint.
This Special Issue focuses on the corrosion and wear resistance, passivation behavior, and advanced applications of HEAs. HEAs represent a paradigm shift in alloy design; their vast compositional spaces and distinctive microstructural features confer exceptional performance in harsh environments. We invite original contributions addressing the following topics: fundamental mechanisms of corrosion resistance and passive film formation, encompassing the governing roles of alloy composition, microstructure, and environmental factors in passivation stability; tribocorrosion, wear behavior under coupled mechanical and chemical loading, and the development of HEA-based coatings and thin films for protective applications; and advanced applications of HEAs in extreme environments such as energy systems, marine engineering, and biomedical implants, where the synergy of corrosion resistance, mechanical integrity, and functional performance is critical. Both experimental investigations and theoretical modeling that advance the understanding of composition–structure–property relationships in HEAs are encouraged.
Research and academic areas covered by this Special Issue include but are not limited to materials science, corrosion science, surface engineering, electrochemistry, and mechanical engineering.

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 250 words) can be sent to the Editorial Office for assessment.
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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials 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 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.
