Special Issue Information

Dear Colleagues,

The fourth industrial revolution has arrived, codenamed Industry 4.0. The ideas related to this new industrial wave, focused on cyberphysical systems, artificial intelligence, and big data processing, will soon change our lives and social relations. However, in addition to high-tech IT solutions, cyberphysical systems cannot exist as pure software and demand equally advanced physical components.

Advanced materials with extraordinary tribological properties will decide on the efficiency of robots, whereas smart and sensitive materials will determine the efficiency of sensing systems feeding artificial intelligence with necessary data. Robust and adaptive structures will enable flexibility of industrial production lines, while self-healing materials will cut the time costs of maintenance procedures. Functional and smart materials will be the key elements of the industry of the future.

Nonetheless, the importance of efforts on materials development seems to be underestimated in the implementation of Industry 4.0 ideas. This Special Issue will be a step toward filling this gap, enabling the exchange of ideas and presentation of new achievements to the global scientific community.

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.

In this work, simulations of friction at the atomic level were performed to evaluate the influence of inclusions coming from metallic nanoadditives in the friction pair. The simple 2D model was applied considering appropriate values of Lennard–Jones potential parameters for given sets of interacting atoms. The real sliding pairs were replaced by effective equivalents consisting of several atoms. The calculations were based on the pseudo-static approximation. The simplicity of the model enabled to repeat the fast calculations in a very wide range of local pressures and for several types of atomic tribopairs. The performed simulations demonstrated a strong dependence of the coefficient of friction (COF) on the atomic environment of the atoms constituting a tribopair. It was confirmed theoretically that the Mo-Fe pair is characterized by lower atomic COF than Fe-Fe, Cu-Fe, and Ag-Fe pairs. This points to the great applicational potential of metallic molybdenum coating applications in tribological systems. Moreover, it was demonstrated that, although Cu-Cu and Ag-Ag pairs are characterized by relatively high COF, they lower the friction as inclusions in Fe surfaces. Full article
