报告简介:
Friction is ubiquitous in industrial operations and daily life, playing a crucial role in ensuring the stable operation of industrial machinery and enhancing the performance of mechanical components. Tribology, as an independent discipline, was formally established in the 1960s. Jost explicitly defined it as: "The science and related technology that studies the generation, variation, and development of various phenomena on surfaces in relative motion and interaction, with a primary focus on friction, wear, lubrication, and related phenomena." Globally, 23% of the world's total energy is consumed by friction and wear, and approximately 70% of mechanical systems fail due to surface damage or wear. Thus, against the backdrop of severe global challenges related to resources, energy, and the environment, the research, application, and dissemination of tribology deserve significant attention. The speaker will review the understanding of friction from a historical perspective, discussing the general behavior of friction, particularly the evolving nature of sliding interfaces and their impact on friction and wear. Additionally, the presentation will explore the effect of particles on friction from macroscopic, microscopic, and nanoscopic viewpoints, covering scenarios with and without particles, friction at the atomic scale, and the transient characteristics of friction.
