Special Issue Information
Dear Colleagues,
An interface can be defined as a transition between different phases of matter. In a tribological contact, interfaces have the specificity to be under motion, making studies very complicated. Furthermore, interfaces can be of different types depending on the considered tribosystems: solid/solid, solid/gas/solid or solid/liquid/solid. Moreover, under certain conditions, chemical reactions could occur within these interfaces and generate a new compound called a tribofilm due to a tribochemical process. This tribofilm, with a thickness of only few nanometers in some cases, is able to control both wear and friction in the contact. The understanding of tribochemical phenomena is an actual key scientific challenge that this Special Issue proposes to address.
It is important to highlight that several parameters influence tribochemical processes: i) the chemical types of molecules present in the liquid or gas environment of the contact; ii) the nature and morphology of the solid surfaces involved in the contact; and iii) the contact conditions. To study such processes, friction tests and post-mortem characterization (topography, physico-chemical composition, mechanical properties, structure, etc.) are commonly performed. Advanced surface analytical tools, in-situ experimental techniques and computational chemistry tools have recently provided new input for the understanding of such phenomena.
This Special Issue aims to publish the latest developments in the field of tribochemistry. Research articles dedicated to any kind of tribochemical phenomena under dry or fluid lubrication and involving different types of lubricant additives, coatings, gas, etc., will be of great interest to this Special Issue. Tailoring surfaces to optimize tribochemical reactivity is also considered an interesting aspect. Advanced in-situ tribometry studies, recent developments of tribofilm characterization techniques, and modeling studies are also highly welcome.

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. Lubricants 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.
