Bridging Scales: From Metals and Alloys to 2D Materials in Tribology and Corrosion

Dear Colleagues,

The performance and longevity of engineering materials are fundamentally governed by their resistance to degradation in demanding environments. This Special Issue, "Bridging Scales: From Metals and Alloys to 2D Materials in Tribology and Corrosion", aims to explore the intricate interplay between mechanical wear (tribology) and chemical/electrochemical attack (corrosion), with a specific focus on the role of hydrogen and the emergence of novel 2D materials.

Metals and alloys—the workhorses of industry—are persistently challenged by synergistic degradation mechanisms. Processes such as corrosion, stress corrosion cracking (SCC), wear, and hydrogen embrittlement are major causes of catastrophic failure. The permeation and interaction of hydrogen with microstructures often accelerate these failure pathways, leading to unpredictable material degradation. Concurrently, the field of tribology is critical for understanding friction, wear, and lubrication, which are essential for the moving components often operating in corrosive settings.

In recent years, two-dimensional (2D materials) like graphene, MXenes, and h-BN have emerged as revolutionary materials for surface engineering. Their exceptional properties offer unprecedented opportunities for developing next-generation protective coatings, lubricants, and corrosion inhibitors. This Special Issue seeks to bridge the traditional knowledge of metallurgy with the novel capabilities of 2D materials to address these multifaceted challenges.

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. 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.
