Magnetic abrasive used for the internal finishing of capillary tubes is a composite particle, consisting of iron and Al_2O_3 abrasive grains. The irregularity of the magnetic abrasive shape, due to the mechanical refining process, results in the non-uniform depth of cut of the abrasive and restricts the improvement of the finished surface quality. These difficulties of the existing magnetic abrasive have resulted in a narrow range of finishing performance. Moreover, the irregularity of the magnetic abrasive shape brings the difficulty in merely introducing the magnetic abrasive into the capillary tubes. To break through the mentioned difficulties, this research develops a spherical iron-based magnetic abrasive made using by plasma spray, which carries Al_2O_3 grains on the surface. This paper discusses the effects of the methods of mixing the iron particles and abrasive grains, a pre-process to the plasma spray, on the finishing characteristics of the magnetic abrasive.
