Abstract
Carbonyl-iron (CI)-based magnetorheological (MR) fluid containing submicron-sized additive particles was prepared. The flow behavior at a steady shear mode was investigated by comparing flow properties of CI-mineral oil suspensions with and without an additive under the magnetic field strength. To enhance the dispersion stability, submicron-sized organoclay was added to the CI suspensions. The submicron-sized particles, while preserving the magnetic properties, inhibited the sedimentation of the CI particles. In addition, with the precision control of magnetic field strength, we examined the novel features of submicron-sized particle-filled CI suspensions, especially under weak magnetic field strengths, in steady shear modes. A temporal decrease of steady shear viscosity was observed in sweeping magnetic field strengths.
