Special Issue Information

Dear Colleagues,

Wear and friction are inevitably encountered in almost all industrial and technological sectors, resulting in various issues related to material damage or failure, energy loss, the performance and service life of equipment and instruments, high maintenance costs and safety concerns, etc. Friction and wear are complex surface processes, involving mechanical, metallurgical, physical and chemical interactions as well as mutually influenced sub- processes (e.g., environment–wear synergy and wear under the influence of external fields). On the other hand, wear and friction can be manipulated by changing the contact conditions and utilizing the external fields, e.g., variations in wear and friction in magnific fields. There has been exciting progress in tribological research and applications in this area, including that relating to the following: control wear and friction in electrical vehicles and trains, tuning wear using magnetic fields, wear control in nuclear-energy systems, friction control by surface texturing, tribological prediction via AI and machine learning techniques and analysis of the fundamentals of tribo-materials via first-principles calculations and molecular dynamics simulations.

We welcome to this Special Issue manuscripts that report on studies concerning recent progress in the tribological research and applications of metallic materials, including, but not limited to, the following topics:

  • The fundamentals of the wear and friction of metallic materials;
  • The tribology of armor materials;
  • Wear and friction in energy production, e.g., nuclear reactors;
  • Wear and friction in external fields, e.g., electrical and magnetical fields and energy field-assisted machining;
  • Progress in bionic tribology;
  • Progress in tribology in electronic devices;
  • AI and machine learning for tribo-material design and prediction;
  • Computational tribo-materials and tribological processes;
  • The additive manufacturing of tribo-materials;
  • Progress in tribological research in the transportation sector;
  • Wear and friction in electrical vehicles and trains;
  • Surface engineering for friction and wear control.

While the addition of WC increases the hardness and wear resistance of coatings, an excessive WC content can also induce crack initiation and propagation, increasing brittleness and leading to premature failure. Therefore, in this study, WC particles were incorporated into nickel-based coatings by plasma-arc surfacing to optimize their content and distribution, balancing their tensile properties and wear resistance. The coatings were comprehensively evaluated through microstructural analysis, hardness testing, wear resistance assessment, and tensile testing. The results show that as the mass fraction of WC increased from 45% to 65%, the increase in carbon significantly promoted the formation of M7C3, M6C, and M23C6 carbides and suppressed the formation of the γ-phase. The microstructural analysis showed that the content of massive carbides increased significantly with the increasing WC content, and the XPS analysis further confirmed that the changes in the WC and Cr7C3 phases were particularly pronounced in the high-WC coating. The 65% WC coating showed higher hardness (a 232 increase in HV1.0), a lower and more stable coefficient of friction (0.42), and better wear resistance than the 45% WC coating, with a wear rate of 3.329 × 10−6 mm3/(N·m)−1, which was 3.709 × 10−6 mm3/(N·m)−1 lower than that of the 45% WC coating. The conventional tensile test results show that the maximum stress and strain of the 45% WC coating were 71% and 36% higher than those of the 65% WC coating, respectively. In addition, the 45% WC coating exhibited better ductility and quasi-cleavage characteristics, whereas the 65% WC coating showed typical brittle cracking behavior. The results of the field tensile tests also showed that the fracture time of the 65% WC coating was 27 s shorter than that of the 45% WC coating. Overall, the 45% WC coating had a good combination of strength and toughness. Full article
