钕铁硼磁体表面化学镀 Ni-Cu-P 合金工艺及性能研究

摘要

This paper studies the process of plating Ni‐Cu‐P alloy on Nd‐Fe‐B magnet surface .The scanning electron microscopy (SEM ) pictures display Ni‐Cu‐P alloy coating is homogeneous cell structure .X‐ray diffraction pattern analysis results show this coating is in microcrystalline state .Therefore ,the Ni‐Cu‐P alloy coating has good corrosion resistance and wear resistance ,being able to meet the requirement of industrial application .%　　研究了Nd－Fe－B磁体表面化学镀Ni－Cu－P合金的工艺过程。扫描电镜照片显示Ni－Cu－P合金镀层呈胞状结构，颗粒较均匀；X射线衍射图谱分析，该镀层为微晶状态。通过该工艺得到的 Ni －Cu－P合金镀层有良好的耐腐蚀性和耐磨性能，符合工业应用要求。
