Experimental investigation to effects of oleic acid and lauric acid on stabilization of magnetorheological fluids

The effects of oleic acid and lauric acid on the stabilization of magnetorheological fluids(MRF) were investigated experimentally.Several groups of samples were prepared,with both lauric acid and oleic acid as additives.The variations of the zero-field viscosity,mechanical property and sedimentation rate of these samples against time were tested,and the effects of volume fractions of lauric acid,oleic acid and carbonyl iron on the stabilization and mechanical property of the MRF samples were studied.The results indicated that the proper addition of lauric acid and oleic acid could significantly improve the mechanical property of magnetorheological fluids.
