摘要
外加电磁场是改善摩擦副摩擦学性能的途径之一。从外加电磁场对位错运动的促进、接触表面氧化的增强和磨屑的细化氧化3个方面,综述了电磁场对金属材料摩擦副摩擦学性能改善的机理,介绍了外加电磁场类型、磁场强度、磁场施加方向、磁场频率以及摩擦副材料的磁导率大小及差异、外加磁性颗粒尺度对摩擦副摩擦磨损的影响,指出了未来电磁场抗磨减摩的研究方向。
Applying an external electromagnetic field is one of the ways to improve the tribological performance of the friction pair.From three aspects of the promotion of dislocation movement,the enhancement of the oxidation of the contact surface and the refinement and oxidation of the wear debris by the external electromagnetic field,the mechanism of the electromagnetic field improving the tribological performance of the metal material friction pair is reviewed.The influence of the external electromagnetic field type,the magnetic field strength,the magnetic field application direction,the magnetic field frequency,the magnitude and difference of magnetic permeability of the friction pair material and the size of the external magnetic particle on the friction and wear of the friction pair is discribed.The future research direction on the anti-friction of the electromagnetic field is pointed out.
