Special Issue Information

Dear Colleagues,

Scientists have studied friction and wear from the late fifteenth century, when Leonardo da Vinci developed the first friction model. More recently, in 1966, H. Peter Jost coined the new word "Tribology" to indicate the combined effect of friction and wear that influences the strength of materials. Previous work on this topic underlined the multidisciplinary nature of friction and wear, which requires knowledge drawn from contact mechanics, materials science, chemistry and physics in general. Friction is one of the main sources of energy dissipation between the contact surfaces and the dissipation of energy is the main cause of wear.

Although the tribology in the broadest sense has studied for so long all the facets of this complex subject have not yet been thoroughly examined and research in this field is going on all over the world.

Materials is providing a Special Issue that is intended to be a means for researchers and engineers of different disciplines to publish and exchange the latest results of their research. This Special Issue will focus on progress in understanding both the fundamental and applied aspects of wear and friction of materials. With the aim of highlighting this concept, this special issue will focus on the following topics:

  • Wear: Theory, Modeling and Simulation.
  • Wear: Testing and Monitoring.
  • Friction and Wear under Vibratory Contact.
  • Engine Tribology and wear at high temperature.
  • Wear of Coatings.
  • Wear of Tools.
  • Tribocorrosion.
  • Role of Third Bodies during Wear.
  • Others.

We warmly invite you to submit a manuscript(s) for this Special Issue. Full papers, communications, and reviews are all welcome.

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.

The pin-on-disc test is a standard sliding wear test used to analyse sliding properties, including wear contour and wear volume. In this study, long-term laboratory test performance is compared with a short-term numerical model. A discrete element method (DEM) approach combined with an Archard wear model and a deformable geometry technique is used. The effect of mesh size on wear results is evaluated, and a scaling factor is defined to relate the number of revolutions between the experiment and the numerical model. The simulation results indicate that the mesh size of the disc has a significant effect on the wear contour. The wear depth and wear width follow a normal distribution after experiencing a run-in phase, while the wear volume has a quadratic relation with the number of revolutions. For the studied material combination, the calibration of the wear coefficient shows that the wear volume of the pin-on-disc test accurately matches the simulation results for a minimum of eight revolutions with a wear coefficient lower than 2 × 10−11 Pa−1.
