摘要
A type of sintered Nd—Fe—B permanent magnet with high corrosion resistance is produced by dual alloy method. The method comprises the following steps: preparing the powders of master phase alloy and intergranular phase alloy respectively, mixing the powders, compacting the powders in magnetic field, sintering the compacted body at 1050˜1125° C., and annealing at 920-1020° C. and 500-650° C. successively.
