摘　　要：通过调整不同颗粒度之间的搭配 ,研究颗粒度的变化对各向同性NdFeB粘结磁体密度和各项磁性能指标的影响 实验结果表明 ,小颗粒的加入使粘结磁体的密度有所提高 ,适量小颗粒的加入有利于提高磁性能指标 ,但随着加入量的增多 。By arranging the percentage of two NdFeB powders with different particle size,the effect of particle size adjustment on the density and the magnetic properties was investigated.The results indicate that the addition of small size powder can improve the density of bonded magnets.Appropriate percent of small size powder can remarkably improve the properties of bonded magnets.All kinds of properties decrease with the increase in the percent of small size powder.

关 键 词：颗粒度 NDFEB粘结磁体 磁性能
