Abstract

In this study, magnetic abrasives were obtained by crushing and sieving sintered iron-silicon carbide (Fe-SiC) composites. Fe and SiC powders with different mesh numbers were pre-compacted using different pressures and then sintered at various temperatures and with different holding times. The dispersion uniformity of the SiC powder was improved through surface modification using polyethylene glycol (PEG) 300. The resulting magnetic abrasives were characterized in terms of phase composition, density, relative permeability, and microstructure; this was followed by a comprehensive analysis to reveal the optimal processing parameters. The ideal combination of process parameters for preparing SiC magnetic-abrasive grains for the magnetic induction-wire sawing process was obtained, which are preparation load of 60 kN, a SiC mesh number of 1,500, a sintering temperature of 1100°C, and a holding time of 4 h.
