Special Issue Information

Dear Colleagues,

We cordially invite you to submit your new publication on the analysis of the mechanism of friction and wear (fretting and sliding wear) of metals and alloys in the transition points from mild to severe wear during dry friction and the lubricant conditions including galling and seizure.

We also expect interesting publications on the interrelation between the parameters of contact mechanics and the variation of the deformed structure. The effect of precipitation and phase transformation in metal and alloys on friction and wear is an important part of our future discussions.

Special attention will also be devoted to the lubricant mechanisms in relation to the parameters of contact mechanics and microstructural variations in surface layers. The effect of the microstructure of metals and alloys on the contact conditions, friction, and wear parameters will be considered.

In addition, the application of new lubricants and new coatings to improve the friction and wear properties of metals and alloys under conditions close to engineering conditions can also be a part of the presented works. New models for the prediction of friction and wear of metals and alloys would be appreciated.

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.

This work aims to demonstrate the discrepancy between the results achieved in the application of ball-on-flat devices. Meanwhile, the interaction between contact parameters and the morphology of friction surfaces will be considered. Flattening depends on the mechanical properties of contact materials and the variation in the deformed structure in surface layers. To evaluate the interaction between roughness parameters and contact pressure, wear, and morphology of the surfaces, a ball-on-disk rig was applied. The average groove sizes were measured on micro- and macroscales. The relation between groove sizes on micro- and macro scales is close to the same. The flattening sinusoidal ball-on-flat model was considered. The real friction and wear tests were used to analyze plastic deformation by accounting for dislocation gliding and the interaction between neighboring asperities. The relation of shear stresses to the interference of rough asperities was established. The effective plastic strain gradient was evaluated. The formation of a highly effective plastic strain gradient is associated with a high dislocation density. The effect of dislocation density on the hardening–softening of surface layers is considered. Full article
