“…2) despite rather high content of FeO oxide in SL (B =1.23; Table 1). The possibility of SL deformation similarly to a viscous liquid is noted elsewhere [5] but the occurrence of a liquid phase on a sliding surface has been observed experimentally and reported by authors [6]. In general case there is no clear understanding of the reasons for generation of liquid.…”

Dry sliding of the sintered composites of compositions Cu-graphite-Fe and Cu-Fe against steel at the contact current density higher 100 A/cm2 has been carried out. The presence of FeO oxide in surface layer was shown. The low content of FeO oxide resulted in high wear intensity. Formation of a liquid phase on a sliding surface was observed. Wear intensity was low in the presence of a liquid phase on the worn surface.

“…The generation of the arc will accelerate the melting and gasification of the contact surface, generate erosion pits, thermal stress cracks, and material peeling, and intensify the wear of materials [133,134]. Fadin et al [135][136][137] analyzed the current-carrying friction and wear process from the atomic point of view and found that in the microscopic region near the contact point, the atoms were in a highly excited state. Plastic deformation will form, viscous fluid will form in the microscopic region, and stress relaxation will occur in the subsequent plastic deformation process, which significantly improves the wear resistance of the contact surface.…”

As aerospace, electrified railway, weapon equipment manufacturing, and other fields have leapt forward, the operating environment of current-carrying friction pairs is becoming increasingly severe, and research on the current-carrying friction and wear theory and its vital technologies are progressively in demand. This study summarizes the relevant research on the current-carrying friction and wear. In this study, the essential characteristics and classification of current-carrying friction and wear are summarized, the effect of working parameters on current-carrying friction and wear performance is clarified, and the generation mechanism, failure mechanism, and factors of current-carrying friction and wear are emphatically investigated. Moreover, the mechanism of arc generation and the effect of environmental conditions and surface facial masks on the friction and wear process are summarized. This paper also introduces the preparation technology of a conductive wear-resistant self-lubricating material, the main factors affecting the conductive wear-resistant property of the coating, and the action mechanism. The simulation and prediction results of the current-carrying friction and wear temperature field and the wear amount are presented. Finally, the problems in the current-carrying friction and wear research are classified, and future research directions in this field are proposed. The future’s critical development and improvement directions are also proposed from the aspects of developing coating quality evaluation equipment, optimizing the coating quality, and studying the coating self-lubricating mechanisms.
