| 中文摘要: |
| 与传统润滑剂相比，磁性液体因其具有特殊的可控润滑效应，一直是国内外学者研究的热点。概述了磁性液体的组成及其所具有的基本特性，着重从理论和实验两方面回顾了国内外学者在磁性液体润滑技术方面所取得的研究成果及最新进展。在理论方面，分析了润滑边界条件、磁场强度及磁性颗粒等因素对于磁性液体压力分布和承载能力的影响。在实验方面，探讨了采用不同手段改变其粘度进而对最终润滑性能的影响，突出了磁性液体作为一种新型功能化润滑剂在润滑性能和承载能力上的优势。此外，受永磁铁空间布局的限制，引入了磁性表面织构配合磁性液体润滑的前沿思想，重点阐述了磁液润滑下磁性表面织构的工作机理，通过实验发现了其在高速下具有减摩促润滑性能，并对其未来广阔的应用前景进行了展望。 |

| Compared with traditional lubricants, magnetic liquid has been a research focus of scholars at home and abroad due to its special controllable lubrication effect. Composition and basic characteristics of magnetic fluid were introduced. Research achievements and recent progress made by scholars at home and abroad regarding magnetic fluid lubrication technology in terms of theory and experiment. In terms of theory, effects of boundary conditions, magnetic field intensity and magnetic particle on pressure distribution and load capacity of magnetic fluid were analyzed. In terms of experiment, effects of changing viscosity in different ways on final lubricating property were discussed. Advantages of magnetic liquid as a new functional lubricant in lubricating property and load capacity were highlighted. In addition, in order to resolve the restriction of permanent magnet space layout, a new perspective of magnetic surface texture in harmony with magnetic fluid lubrication was introduced. Working mechanism of the magnetic surface texture was illustrated emphatically. Experiment showed that the technology could reduce friction and improve lubricating property at high velocity. Besides, promising application prospect of this technology was expected. |
