Special Issue Information

Dear Colleagues,

The study on the characterization and mechanisms of friction and wear phenomena is always a matter of central focus in tribology. Since tribo-materials and friction systems have a wide variety, their properties and mechanisms have necessarily become complicated. Along with advances in measurement and analysis technologies in recent years, the essence of friction and wear phenomena will become clearer through a number of studies. For building a sustainable society for the future, it is necessary to study and develop the optimal tribological systems with a social environment.

In the Special Issue entitled "Characterization and Mechanisms of Friction and Wear Phenomena," original papers focusing on evaluating tribological properties and elucidating tribological processes from multifaceted viewpoints such as friction and wear tests, in situ measurements, and modeling and simulation in tribology are welcomed. Furthermore, the papers on the latest topics will be welcome as they aim for a deeper understanding of friction and wear phenomena in various tribo-materials and tribological systems. We hope that this Special Issue will be utilized to make a breakthrough in realizing a sustainable society for the future. We are looking forward to receiving your submissions.

In order to confirm the vibrate compaction energy, the indoor vibration compaction was conducted. Indoor vibration compactor was used to compact skeleton dense cement stabilized aggregate. The acceleration and displacement of the indenter and compaction pressure during the compaction process were measured. The bounce model and the hysteresis curve based on measurement parameters were used to calculate the compaction energy. Three vibration compaction energy were affirmed as: energy of the machinery itself (Eself), energy transmitted from machinery to compacted material (Et) and energy stored by compacted materials (Es). The energy Eself was about 40 J (joule). During each compaction process, energy Et was only 1–1.8 J. In a one-minute compaction process, 2500 J of energy would be transmitted, but only 38 J could be stored by the compacted material. Full article

A method based on acoustic emission (AE) sensing in which two AE sensors are used to measure the tribological characteristics of two interacting friction materials simultaneously in real time was assessed for the in situ measurement and evaluation of the wear process of silver plating. AE sensors were attached to a silver-plated pin and a silver-plated plate, and the two AE signals were measured simultaneously on a pin-on-plate-type reciprocating sliding tester. The resulting changes in the AE signal could be classified into three phases. Surface observations and energy-dispersive X-ray spectroscopy analyses showed that the wear of the silver-plating layer progressed in Phase I, the nickel intermediate layer was exposed and wear of the nickel progressed in Phase II, and the contact electrical resistance increased and the copper substrate was exposed in Phase III. In summary, the wear process of a silver-plating layer, which cannot be identified from the changes in the frictional resistance or the contact electric resistance, can be detected from changes in the dual AE signals. Furthermore, changes in the wear state of both the pin and plate specimens can be identified from differences in the amplitudes of the AE signals and the timing of their detection. Full article
