摘要：
This paper presents the preparation of magnetorheological fluids (MRF) starting from iron powder in size of 4-6 mu m, silicone oil and a few commercial additives. The structure and magnetic properties of iron powder are evaluated by X-rays diffractions and hysteresis curves. The MRFs were selected through gamma radiation transmission, upon the determination of the sedimentation rate in the gravitational field. The dispersion of MRFs particles is presented using the electron transmission microscopy. The magnetorheological behavior in dynamic conditions was tested in a device specially designed for that purpose.
