摘要
超低摩擦是纳米技术诞生后在摩擦学中近几年蓬勃发展的新领域。超低摩擦集成了量子力学、量子化学、纳米技术、分子动力学,为现代精密、低能耗、长寿命机械设计提供了强有力的摩擦学支撑。根据近几年超低摩擦的发展现状,分析了当前超低摩擦的理论及其局限性,阐明了当前产生超低摩擦的条件和材料特征,指出随着超低摩擦理论、技术和材料的大胆创新,超低摩擦必将在常规乃至恶劣工况下运行的装备上得到迅速应用。
The theories about super -low friction and their restrictions were analyzed with respect to the state-of-art and research development of super-low friction. The conditions to generate super-low friction and the materials characteristics were described as well. It was pointed out that super-low friction as a thriving frontier in tribology had been extensively focused on since the birth of nano-technology, and great progress had been made in the research of super-low friction. Since the study on super-low friction is closely related to the fundamental theories and technologies in multi-disciplines such as quantum mechanics, quantum chemistry, nano-technology, and molecular dynamics etc., it could provide powerful tribological support to the design of modern machines with precision, low energy loss and long life. And it could be rationally expected that with the innovation of relevant theory, technology and materials, super-low friction would be widely applied to the equipments working under ordinary and even harsh conditions.
