Preparation of Magnetic Abrasive by Sintering Method
In this paper, ferrosilicon powder was used as the ferromagnetic phase, corundum powder as the abrasive phase, high temperature inorganic binder as the adhesive, and after the ferrosilicon powder was modified, a series of magnetic abrasive was obtained by sintering method. Scanning electron microscope (SEM) and Energy dispersive spectrometer (EDS) were respectively used to characterize the morphology and elemental composition of magnetic abrasive. and through experiments carried out on the magnetic abrasive grinding performance testing and durability analysis. The experimental results showed that the magnetic abrasive prepared had good polishing ability and longer using time, and the surface roughness of the grinding sample can reach 0.12μm and the using time is up to 25 min.
