Special Issue Information

Dear Colleagues,

We are delighted invite submissions for the Special Issue “Self-Lubrication Technologies and Tribology Behavior in High-Performance Mechanical Components”. Our aim with this Special Issue is to compile a comprehensive collection of the most recent, cutting-edge developments and innovations in this field.

With the continuous development of high-end equipment manufacturing towards high speed, heavy load, high precision, and extreme working conditions (high/low temperature, vacuum, radiation), traditional lubrication methods have faced enormous challenges. Developing self-lubricating technologies and materials with low friction, high wear resistance, long lifespans, and environmental adaptability has become a key core for improving the reliability and energy efficiency of mechanical systems. This Special Issue will showcase the latest achievements in research and cutting-edge progress in this field and promote academic exchange and technological transformation. We invite researchers, engineers, and scholars in this field to submit papers. The topics of the manuscripts can include, but are not limited to, the following areas: new self-lubricating materials and coatings, surface texturing and modification techniques, frictional mechanisms and simulations, advanced characterization and in-situ monitoring, performance research under extreme working conditions, and so on.

We are particularly eager to receive submissions from a diverse range of scholars, industry researchers, and practitioners who are currently contributing to this rapidly evolving field. This call for papers represents an exceptional opportunity for your work to reach a broad audience and for you to engage with others in your field.

Metal-based electrical contact materials (ECMs) are essential in switching devices and rotating electrical machines, where sliding contacts enable reliable current transmission under motion. These materials must exhibit high conductivity, low friction, and wear resistance to meet industrial demands. However, their reliability is limited by wear, oxidation, arcing, and other failure mechanisms that increase contact resistance and degrade performance. To address these issues, researchers have developed self-lubricating metal matrix composites (MMCs), particularly copper (Cu) and silver (Ag)-based composites reinforced with solid lubricants such as molybdenum disulfide, tungsten disulfide, graphite, carbon nanotubes, graphene, and its derivatives. While Cu and Ag provide excellent conductivity, each has trade-offs in cost, oxidation resistance, and mechanical strength. Strategies for improving reliability involve material optimization, surface treatments, lubrication, contact design modifications, and advanced manufacturing. Although MMCs are widely reviewed, self-lubricating Ag matrix nanocomposites (AgMNCs) for sliding contacts are underexplored. This review highlights recent progress in AgMNCs produced by conventional or modern powder metallurgy techniques, focusing on the role of solid lubricants, testing conditions, and microstructure on tribological performance. Wear mechanisms, research gaps, and future directions are discussed, highlighting pathways toward the development of reliable sliding contacts. Full article
