摘要

介绍了在Ni-Fe-B基体上电沉积Ni-Fe合金镀层耐蚀性的研究成果。研究结果表明:Nd-Fe-B磁体上Ni-Fe合金镀层的相结构是α、γ双相合金

孔隙少；镀层的光亮性

耐蚀性与纯镍镀层相当。采用化学镀铜做过镀层

可进一步降低Ni-Fe合金镀层的孔隙率

提高合金镀层的耐蚀性。

Abstract

The electrodeposition of Ni-Fe Alloy on the matrix of Nd-Fe-B was investigated in detail. The phase structure was γ and α phase

the percentage of iron in the alloy deposits ranged for 18% to 25%. The corrosion resistance of Ni-Fe ally deposits plated directly on the matix of Nd-Fe-B was in proportion to Ni deposits. The corrosion resistance of Ni-Fe alloy deposits previously plated Cu on the matrix was greater than that of Ni deposit on Nd-Fe-B matix.
