Special Issue Information
Dear Colleagues,
Numerous researchers have joined their efforts on the challenges that modern engineering demands, such as the importance of controlling the wear rate in kinematic joints. The complexity of the multiple variables involved in the wear processes and the importance of the compression of the main mechanisms and sub-mechanisms to estimate the useful life of machine elements in industrial applications make it attractive. Nanostructured ceramic coatings are increasingly used due to their excellent mechanical properties, being able to extend the lifetime of machine elements, but they have their limitations and problems, such as their high fragility, porosity, low cohesion between splats, and low adhesion between coating and substrate compared to metal coatings. It is of great relevance to improve the tribological behavior of nanostructured ceramic coatings modified with additions of solid/liquid lubricants (graphene, graphite, or MoS2 PFEP/PFA) and to further study their influence on the load carrying capacity in the transition of lubrication regimes and the synergistic effect on the lubricant and compression in the formation of a tribofilm capable of separating the two surfaces in contact, reducing friction, and consequently, wear. An important aspect to be considered is the need to continue studying the optimal hardness ratio of the frictional pair and how it affects tribological behavior (lubrication regimes and Stribeck curve).

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.
