“…SiC, Al2O3, and B2O3 abrasive particles were added at 35% to the prepared binder medium and mixed uniformly to obtain different abrasive particles. Guang et al 6 using the method of combining plasma melting metal powder with shot blasting abrasives, high-performance spherical iron-based Al2O3 magnetic abrasives were prepared, and micromorphology, phase composition, the bonding method, magnetic conductivity, and particle size distribution of the magnetic abrasives were analyzed. Bin et al 7 used chemical composite plating to prepare diamond magnetic abrasive particles by mixing iron particles with micro-diamond particles and predicted the adsorption rate of micro-diamond particles on the iron matrix by establishing a mathematical model.…”

Magnetic elastic abrasive particles are a new type of particle that combine the characteristics of magnetic abrasive particles and elastic abrasive particles by embedding magnetic media and abrasive particles in a particular proportion into a flexible polymer to form particles with a specific shape. First, a method for preparing magnetic elastic abrasive particles is proposed. A representative micro-unit model of magnetic elastic abrasive particles is established using 3DMAX software. The finite element software ABAQUS is used to analyze the micromechanical properties of magnetic elastic abrasive particles with silicon carbide (SiC) and alumina (Al2O3) particles as the abrasive phase, respectively. Secondly, based on the characteristics of double disk magnetic force passivation of magnetic elastic abrasive particles, a method is proposed to predict the life of magnetic elastic abrasive particles by predicting the surface roughness of the tool edge. The effects of particle size and abrasive phase on the wear and life of magnetic elastic abrasive particles are studied experimentally. Finally, the magnetic field force is analyzed, and a mathematical model of material removal for magnetic elastic abrasive particles is established based on the characteristics of the mixing phase. The effects of particle size and abrasive degree on material removal volume are studied, and the influence of magnetic elastic abrasive particle size on tool passivation is experimentally analyzed. A comparison is made with the vertical rotary passivation method. The superiority of the magnetic elastic abrasive particle passivation method is verified by examining the passivated tool's edge profile, surface roughness, and service life.

Magnetic abrasive finishing (MAF) is an efficient finishing process method using magnetic abrasive particles (MAPs) as finishing tools. In this study, two iron-based alumina magnetic abrasives with different particle size ranges were synthesized by the plasma molten metal powder and powder jetting method. Characterization of the magnetic abrasives in terms of microscopic morphology, phase composition, magnetic permeability, particle size distribution, and abrasive ability shows that the magnetic abrasives are spherical in shape, that the hard abrasives are combined in the surface layer of the iron matrix and remain sharp, and that the hard abrasives combined in the surface layer of the magnetic abrasives with smaller particle sizes are sparser than those of the magnetic abrasives with larger particle sizes. The magnetic abrasives are composed of α-Fe and Al2O3; the magnetic permeability of the magnetic abrasives having smaller particle sizes is slightly higher than that of the magnetic abrasives having larger particle sizes; the two magnetic abrasives are distributed in a range of different particle sizes; the magnetic abrasives have different magnetic permeabilities, which are higher than those of the larger ones; both magnetic abrasives are distributed in the range of smaller particle sizes; and AZ31B alloy can obtain smaller surface roughness of the workpiece after the grinding process of the magnetic abrasives with a small particle size.
