摘　　要：系统研究了Sm2 Co1 7磁粉含量对NdFeB、AlNiCo、Ferrite粘结复合磁体磁性能的影响 ,并通过多项式拟合的方法分析了实验结果。结果表明 :Sm2 Co1 7和其它三种永磁材料粘结复合时 ,磁粉之间的相互作用对矫顽力的影响较强。添加Sm2 Co1 7来获得高矫顽力的粘结复合永磁材料从经济上来说是不可行的。The effect of addition amount of Sm 2Co 17 powders on the magnetic properties of binary bonded composite magnets was studied. The experimental results were analyzed through polynomial fit. It was shown that when Sm 2Co 17 was blended with other magnetic powders the interaction among magnetic particles was strong. It is not economically suitable to improve the coercive force of magnets through addition of Sm 2Co 17 .
