摘要

磁性材料被广泛应用于磁记录和磁润滑等领域, 聚甲基丙烯酸甲酯因其良好的介电性,能够用作磁性材料的表面涂层. 本文对外磁场作用下, 外加载荷和磁场强度对往复滑动的聚甲基丙烯酸甲酯/磁性薄膜双膜系摩擦性能的影响开展了研究. 实验结果表明: 聚甲基丙烯酸甲酯/磁性双膜体系的摩擦性能随载荷和磁场强度改变而变化; 但在干摩擦和硅油润滑两种模式下, 磁场对其摩擦学性能的影响规律不同. 理论分析了磁场作用下磁场诱发的磁性力与摩擦副物理性质变化对摩擦力和摩擦系数的影响, 与实验结果符合良好. 研究结果为磁性薄膜的界面介质设计与控制提供了依据.

Abstract

Magnetic thin films are widely used in magnetic recording and magnetorheology, and also in magnetic lubrication such as ferromagnetic fluids. Polymethylmethacrylate (PMMA) is used as a coating material on the surface of the magnetic material in an electromagnetic system because of its good dielectric properties. In this study, the tribological behavior of reciprocating motion between ferromagnetic films coated with PMMA films under a magnetic field is evaluated. The system of ferromagnetic films coated with PMMA films based on glass is called ferromagnetic/PMMA double membrane in this paper. Two pieces of membranes in each tribological experiment are absolutely the same. Two kinds of experimental conditions, that is, under dry friction and silicone oil lubrication, are used to investigate the influences of load and magnetic field strength on the friction performance of ferromagnetic/PMMA double membranes. Experimental results show that the magnetic field directly affects the friction performance of a ferromagnetic /PMMA double-film system, and the performance changes with the normal load and intensity of the magnetic field. However, the influence of magnetic field on the tribological property in the dry friction mode is different from that in the silicone oil lubrication mode. The influences of magnetic force and the changes of the physical properties of the friction pair on friction and friction coefficient, which are both induced by the magnetic field, are analyzed. The theoretical analysis results are in good agreement with the experimental date. This work provides a basis for designing and controlling magnetic film interface media.
