“…It is due to the shear-thinning behavior effect for both the MRF samples. When the magnetic field is further increased, the free rotation of the magnetic particles is restricted, which increases the shear viscosity of the MRF samples to form a robust chain-like structure [41].…”

In the present study, the magnetorheological fluid (MRF) samples are prepared using pure carbonyl iron particles (CIPs), CIPs/Claytone APA/Molyvan 855 additive, and friction reducer dispersed in poly-alpha-olefin oil. The scanning electron microscopy reveals that the Claytone additive morphology looks like a surface abundant in small folds, which connect the gaps between the spherical pure CIPs and prevent sedimentation in the MRF. The magnetic saturation properties are investigated through the vibrating sample magnetometer. The pure CIPs MRF shows (M s) value as 146.12 emu/g, and the CIPs/ Claytone APA/Molyvan indicates (M s) as 55.12 emu/g. The magnetorheological flow curves, such as shear stress and viscosity as a function of shear rate, are investigated for the MRF samples through the magnetorheometer. The sedimentation analysis of the MRF is observed by visual inspection and shows that the CIPs/Claytone APA/Molyvan improved the sedimentation rate than the pure CIPs MRF. Finally, the experimental characterization of the prototype monotube MR damper is carried out using the hydraulic dynamic testing machine at 1.5 Hz frequency for damper peak-peak displacement length of ± 5 mm at three intervals of 0 h, 24 h, and 72 h in damper to know the effect on damping force for the prepared MRF samples against the sedimentation rate.

“…In a case where the post yield behaviour becomes nonlinear i.e post yield viscosity of fluid sample either decreases or increases. For this kind of behaviour, Herschel-Bulkley fluid model can be used (Papanastasiou and Boudouvis, 1997;Bae et al, 2017). The equation of Herschel-Bulkley fluid model is given as:…”

The novel controllable behaviour of magnetorheological (MR) fluid is the backbone of magnetorheological fluid-based finishing processes. MR fluid-based finishing processes facilitate better control over finishing forces as the stiffness of MR finishing fluid used in these processes can be controlled in accordance with the applied magnetic field and MR finishing fluid composition. Therefore, a detailed experimental investigation was carried out to find the effect of MR finishing fluid constituents on its yield stress through the Taguchi Design of Experiments. Rheological data obtained from a magneto-rheometer (MCR-102) was characterised by using Bingham plastic, Herschel-Bulkley and Casson's fluid constitutive modelling. The coefficient of regression (R 2) values of Herschel-Bulkley model were found to be best suited for all compositions of MR finishing fluid. Analysis of variance (ANOVA) has been used to find the contribution of selected parameters for improving the response characteristics. The optimized fluid has been then used for the finishing of biocompatible stainless steel AISI 316L, and the finishing results show that the average surface roughness value decreases down to 58 nm.

“…Actively tunable MR fluids consist of Brownian-motion-sustained nano- or microscale soft magnetic particles [ 18 , 19 , 20 ] suspended in nonmagnetic liquids such as mineral oil, natural or mineral fatty acids, silicone oil paraffin, hydrocarbon oil, and silicone oil. Moreover, various additives, such as dispersion stabilizers and surfactants can also be added to MR fluids to prevent gravity sedimentation and enhance stable particle dispersion, increase lubricity, and tune the medium viscosity [ 21 , 22 , 23 , 24 , 25 ]. When an external magnetic field field strength ( H ) is applied, the yield stress and shear viscosity of MR fluids increase by several orders of magnitude, and the MR fluids transform from a fluid-like to a solid-like phase [ 26 , 27 , 28 , 29 ].…”

As a family of smart functional hybrid materials, magnetic polymer composite particles have attracted considerable attention owing to their outstanding magnetism, dispersion stability, and fine biocompatibility. This review covers their magnetorheological properties, namely, flow curve, yield stress, and viscoelastic behavior, along with their synthesis. Preparation methods and characteristics of different types of magnetic composite particles are presented. Apart from the research progress in magnetic polymer composite synthesis, we also discuss prospects of this promising research field.
