| Abstract: | The stability of magnetorheological fluids is extremely important. In this article, the factors affecting the sedimentation stability of dispersion particles in magnetorheological fluids are discussed. Some methods for characterization of dense magnetic particle suspension are presented. The current techniques of improving the subsidence stability in magnetorheological fluids are reviewed in detail. Modifying the surfaces state of microparticles and other methods can be used to effectively prevent the magnetoheological fluids from settling of solid particles. At last, the very promising future of magnetorheological fluids is outlined. |
