Special Issue Information

Dear Colleagues,

This Special Issue is dedicated to research activities concerning the wear and corrosion behaviour of metallic coating materials. Topics of interest may range from fundamental understandings of the wear of corrosion mechanisms to special solutions for their practical application. Materials are exposed to different types of wear (friction, abrasion, erosion) and corrosion attacks (chemical or electrochemical corrosion, molten salt corrosion, high-temperature corrosion), leading to severe material degradation. Therefore, our knowledge of surface engineering must be combined with fundamental information on materials science to understand the observed phenomena and prevent further failure.

In this context, submissions may tackle subjects as diverse as technologies for the deposition of metallic coatings, additive manufacturing methods, or the surface postprocessing of applied coatings using laser or electron beam sources. Functional gradient advanced materials as well as structured surfaces with special chemical, biological, optical, nuclear, aerospace, or other applications have been developed and applied in recent years, but some key problems still need to be elucidated and solved.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

Abstract

In recent decades, batch hot-dip galvanized (HDG) steel has proven itself in practical applications due to the good corrosion resistance of its components. Despite the importance of the mechanical-load-bearing capacity of these coatings, the wear behavior has, so far, only been investigated very sporadically and not systematically, so a quantification of the wear behavior and statements on the mechanisms are vague. Therefore, two body wear tests with bonded abrasive grain were carried out. Varying the friction rolls, load, and total number of cycles, the wear behavior was investigated. The mass loss and the layer thickness reduction were measured at different intervals. After the test, the microstructure in the cross-section and the hardness according to Vickers (0.01 HV) were evaluated. The results showed that the wear behavior of HDG coatings against abrasive loads can be characterized with the selected test conditions. Initially, the applied load removed the soft η-phase. As the total number of cycles increases, the η- and ζ-phases deform plastically, resulting in a lower mass reduction compared to that expected from the measured layer thickness. The characteristic structure of a batch HDG coating with hard intermetallic Zn-Fe phases and an outer pure zinc phase has demonstrated effective resistance to abrasion. Full article

Abstract

Ferrous alloys, particularly steels, form a specialized class of metallic materials extensively employed in industrial sectors to combat deterioration and failures caused by wear. Despite their commendable mechanical properties, steels are not immune to wear-induced degradation. In this context, surface nanocrystallization (SNC) technologies have carved a distinct niche for themselves by enabling the nanostructuring of the surface layer (with grain sizes < 100 nm). This process enhances overall mechanical properties to a level desirable for wear resistance while preserving the chemical composition. Existing literature has consistently highlighted the efficacy of various SNC methods in improving the wear resistance of ferrous alloys, positioning SNC as a promising tool to extend materials’ service life in practical applications. This review provides a comprehensive examination of the SNC techniques employed in surface treatment of ferrous alloys and their impact on wear behavior. We delved into the underlying mechanisms governing wear in SNC-treated Fe-based alloys and concluded with a discussion on current challenges and future perspectives in this evolving field.
