Friction and Wear of Materials Surfaces

Dear Colleagues,

The surface topography is one of the most important factors determining the quality of a surface layer. It defines a set of all overlapping irregularities of surface resulting from the machining processes and wear of materials. Irregularities of surface have varied dimensions, shapes and location. The quality of the surface has a significant impact on the operational properties of machine elements, which are expressed, among others, through: frictional conditions on contact surfaces, corrosion resistance, fatigue strength, contact stresses or tightness of joints. All mechanical, physical, chemical, and geometrical aspects of the surface contact affect the surface interactions and thereby also the tribological characteristics of the system.

A number of scientists studied the effect of surface topography and materials properties on the tribological performance of sliding elements. However accessible papers contain ambiguous and sometimes contradictory opinions about connections between values of surface topography parameters, materials properties and various tribological properties of sliding pairs. In addition a continuous development of measuring equipment makes possible more precision measurement and as a consequence makes possible extended analysis of phenomena taking part on surfaces in frictional contact.

Therefore the aim of this special issue is to collect high-quality research papers that focus on friction and wear of materials surfaces. We are looking forward to receiving your submissions.

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. 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.
