摘　　要：本文针对钕铁硼永磁材料在海洋大气环境中极易被腐蚀的特点,通过化学镀方法在钕铁硼表面沉积镍铜磷镀层,并应用线性极化曲线法和光学显微技术考察了钕铁硼及镀镍铜磷钕铁硼在3.5%NaCl溶液中的腐蚀行为。结果表明,在化学镀镍铜磷后,极大地提升了钕铁硼的耐蚀性。NdFeB permanent magnet materials were corroded easily in the marine atmosphere. In this paper, the Ni-Cu-P coating was deposited by electroless plating on NdFeB permanent magnet and its corrosion resistance was compared with other ternary alloys coating by using linear polarization curves and optical microscope technique.
