Abstract
The present invention provides a permeating treatment method for radially oriented sintered magnet, a magnet, and a composition for magnet permeation, wherein in permeating treatment, the magnet and a target permeation source maintain relative movement therebetween all the time, thus internal defects of the oriented sintered magnet are overcome, and the coercivity and thermal stability of the sintered oriented magnet can be stably improved. Moreover, the present invention, having a controllable permeation amount and uniform permeation, is suitable for permeation reaction of a target permeation source with high viscosity or a low melting point, has a wide range of choice for raw materials, and high utilization ratio of permeation elements substantially with no loss, and low cost, thus being suitable for industrialized popularization and use.
