Characterization of TiO2/Fe3O4 Reinforced Magnetorheological Fluid Blend

In this paper, TiO2 and Fe3O4 nanoparticles (NPs) are infused in magnetorheological fluid and blended in different proportions. This paper aims to find out the magnetorheological fluid with better properties by infusing nanoparticles which makes it dynamic and worthy for variety of applications. Hence the effect of blending of TiO2 and Fe3O4 nanoparticles is studied on magnetorheological fluid properties. The percent of TiO2 and Fe3O4 added in magnetorheological fluid in different weight percentage finalized from research papers. TiO2 percentage is kept constant at 0.2%. Fe3O4 is added viz; 0.5, 1, and 1.5%. For the prepared sample, density is measured and sedimentation rate is calculated after the observation of prepared samples for 80 h. Shear stress, viscosity and magnetic flux density values were measured by using rheometer. In the experimentation, it is found that density is slightly increased due to the weight of iron particles. Out of the prepared blends, S2 i.e. 0.2% TiO2 + 1% Fe3O4 in magnetorheological fluid combination is found with increased viscosity, increased Shear stress and decreased sedimentation rate which is a better option for various magnetorheological applications.
