应用SEM、EDAX观察分析了烧结NdFeB磁体金属Ni镀层麻点、洼坑等缺陷处的基体显微组织，发现镀层缺陷部位磁体显微组织皆为异常粗大晶粒区。从磁体制造工艺角度讨论了镀层缺陷产生的原因，提出了避免镀层缺陷的途径。

Microstructural analysis has been performed of sintered Nd-Fe-B magnets with Ni Plating by means of SEM and EDAX techniques． Experimental results show that abnormally large grains exist in the areas of magnets corresponding to plating defects such as pits． The cause of the formation of plating defects is investigated in the view of production process of sintered Nd-Fe-B magnets， and measures are proposed to avoid such plating defects．
