Special Issue Information
Dear Colleagues,
By alloying, particle reinforcement, heat treatment, and surface engineering, high-strength, gradient interfaces with tailored residual stress and hardness profiles can be engineered on aluminum alloy surfaces. These interfaces raise the shear and plastic-flow thresholds, curb localized yielding, and stabilize tribochemical films, thereby reducing the coefficient of friction (CoF) and wear rate under dry/boundary lubrication. The hardened near-surface layer suppresses adhesive junctions and furrow formation, while controlled deformation and precipitation enhance load-bearing capacity. Complementary strategies—such as anodizing, hard coatings, and textured/chemically patterned surfaces—further improve film adherence and wear resistance. To maximize performance, synergistic optimization of composition, residual stress, roughness, and lubricant chemistry is essential across load–speed–temperature regimes.

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-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.
