“…Without the assistance of weak magnetic eld, the material removal mechanism of polishing ow is consistent with that of shear thickening polishing (Ref 14,16,27,33). As can be seen from the above rheological properties, the thickening property of the polishing ow under this condition is weak, and it cannot provide su cient gripping force for abrasive particles.…”

Shear thickening polishing technology using non-Newtonian polishing uid is a low-cost, low-damage polishing method for the ultra-precision machining of complex curved surfaces. However, the shortcomings of traditional shear thickening polishing uid in polishing e ciency and uid viscosity controllability limit its further application., a novel weak magnetic eld-assisted shear thickening polishing uid (WMFA-STPF) containing carbonyl iron particles (CIPs) is presented in this study, which utilizes its weak magnetorheological effect to strengthen the shear thickening phenomenon. The rheological characteristics of the WMFA-STPF samples were investigated. The results show that WMFA-STPF has good uidity in the low shear rate range and better thickening characteristics in the working shear rate range. In order to verify the high e ciency, high quality and high uniformity polishing ability of the weak magnetic eld-assisted shear thickening polishing technology for the spherical surface of zirconia ceramic workpiece, the contrast polishing experiment was designed and nished. The experimental results show that the weak magnetic eld-assisted thickening effect can achieve high e ciency and high quality polishing of hard and brittle ceramics. After 75 min polishing, the surface damage was effectively improved and eliminated, the surface quality and uniformity were greatly improved, and the material removal rate reached 7.82 μm/h, increased by 156%.

“…In order to further explore the microscopic mechanism of material removal, based on the assumption of the N–S equation and Reynolds equation, the velocity and stress distribution models of the flow field in the polishing zone were established, and then the prediction model of the material removal rate was obtained. 24,25 The rheological constitutive model is the key factor to the accuracy of the predict model. Therefore, it is necessary to characterize the field rheological properties of the dispersion system.…”

“…In addition, STFs integrating structural members are suggested for mechanical systems subjected to cyclic loadings [12][13][14][15]. STF was also benefitted in manufacturing operations using it as a polishing slurry, which takes advantage of thickening viscosity to hold the abrasive particles in the operation [16][17][18][19]. In recent investigations, the multi-phase concept was developed in STF systems which utilize a second particulate phase in the suspensions.…”

Shear thickening fluid (STF) is a very interesting and promising material in several application fields where a different mechanical is demanded based on loading rates, like body armor and vibration insulators. Cork is a natural cellular material by excellence, filled with well-known beneficial effects in terms of insulation and also interesting crashworthiness properties. In this work, cork grains of very small size (0.5-1.0 mm) are added to two different shear thickening suspensions, one of them a fully natural water and cornstarch, and the other based on fumed silica and polyethylene glycol. The rheology of these ecofriendly suspensions was investigated and the influences of including cork grains were discussed. In addition, microscopic analyses were carried out to observe the deformations at each component during the shear thickening phenomenon. Cork grains reduce the load-carrying capacity in the suspensions due to the deformable characteristics of cork. For this reason, shear thickening properties are suppressed in the mixtures. Despite this, it is possible to state that viscosity increase in the mixtures leads to strong particle contacts, and thereby resulting in particle deformations in the main constituent powder as well as in the cork additives due to their softer structures.
