Preparation of white alumina spherical composite magnetic abrasive by gas atomization and rapid solidification

https://doi.org/10.1016/j.scriptamat.2011.05.021Get rights and content

White alumina (WA) spherical composite magnetic abrasive can be prepared directly by a process that combines gas atomization and rapid solidification. The structure and phase composition of this material were characterized by scanning electron microscopy and X-ray diffraction analysis. The results show that the composite magnetic abrasive has good sphericity, and the WA grains are tightly embedded uniformly and densely into the surface layer of matrix which consists of Fe–Si–Al–Ni soft magnetic alloy.

    The magnetic abrasives prepared by this method have high density and long life, but are difficult and costly to crush. The gas atomization and rapid solidification method [12] uses aerosolized powder making equipment combined with high -speed spraying of hard abrasives and rapid coagulation to prepare magnetic abrasives. High grinding capacity and long life are the outstanding features of this method to prepare magnetic abrasives.

    Therefore, we sought to prepare ideal MAPs through gas atomization and rapid solidification. In our previous work, we successfully prepared Al2O3 and SiC/Fe-based spherical MAPs, and applied them to S136 die steel and 316 L stainless steel [10–12]. We found that these MAPs exhibit high sphericity and that the ceramic abrasive distributes uniformly and densely around the iron matrix.
