摘要
磁流变液中的磁性颗粒要求具有高矫顽力、低比重,在相当大的温度范围内保持较高的稳定性。基于以上,综述了各种磁性颗粒的特点、发展历程及其各种物理化学制备方法,阐述了各种制备方法与磁性颗粒结构及性能的关系,对比分析了各种磁性颗粒对磁流变液性能的影响,指出了目前存在的问题,展望了磁性颗粒的制备方法与结构、性能机理的发展趋势。
The magnetic particles of Magnetorheological fluid demand high coercive force,low specific gravity and high stability in a wide temperature range.Based on hereinbefore,this article summarizes the characteris-tics of various magnetic particles,development process and preparations including chemical and physical meth-ods.It illustrates the relation between kinds of preparations and the structure and function of the magnetic par-ticles.Besides,the effect of magnetic particles on magnetorheological fluids was analyzed.Finally it points the shortage of magnetorheological fluids nowadays and make a view on the preparations,function,structure and the process.
