Abstract
Physical characteristics of a magneto-rheological(MR) fluid can be influenced by a magnetic field. MR fluid is a suspension of micrometer-sized magnetic particles in a base liquid such as oil. Therefore, the key issue is dispersion stability because density of micrometer-sized magnetic particles are different from that of oil. In the present study, dispersion stability and physical characteristics along chemical compositions of MR fluid are investigated. 216 kinds of MR fluids are made by using magnetic powder(#2), surfactant(#2), base oil(#2), functional additive(#3), density(#3) and viscosity(#3). From experimental results, SEM photograph, magnetic flux density, supernatant and sediment of 216 kinds of MR fluids are obtained.
