|Abstract:||The surface modification of soft carbonyl particle (CIPs) based magnetorheological (MR) fluids is the most popular method to solve sedimentation problem. In this present work,the two MR fluidswere prepared using pure CIPs (MRF#1) and Tragacanth gum coated CIPs (Tg/ CIPs) (MRF#2) are dispersed in hydraulic oil as a carrier fluid. The morphology, elemental composition and magnetic saturation properties were investigated using scanning electron microscopy (SEM),energy dispersive spectroscopy (EDS), superconducting quantum interface device (SQUID) analysis respectively. In addition to that,chemical bonding and thermal oxidation resistance of CIPs and (Tg/ CIPs) was analyzed using Fourier-transform infrared spectroscopy FTIR and thermo-gravimetric analyzer (TGA). The rheological properties of CIPs and Tg/CIPs based MRFs was tested to determine the flow behaviourat different currents 0,1,2,3 and 4Amps. The experimental results found that Tg/CIPs based MRFs is having higher yield stress of about (16kPa) than pure CIPs (15kPa). The decrease in the density of Tg/CIPs showed better sedimentation ratio (i.e r=91%) than the pure CIPs based MRFs which was observed using naked eye visual method. © 2020 Author(s).|
