摘　　要：在NdFeB永磁体表面化学镀Ni-Cu-P合金镀层,研究了镀液配方对镀层性能的影响。结果表明:镀层表面形貌呈致密的胞状结构,Ni,Cu,P元素分布均匀;随着镀层中Cu和P的质量分数的变化,镀层结构分别由晶态、混晶态和非晶态组成;晶态镀层的硬度最高、结合力最好,非晶态镀层的耐蚀性最好。An electroless Ni-Cu-P coating was plated on the surface of NdFeB permanent magnet.The effects of bath formula on the properties of the coating were investigated.The results show that the surface morphology of the coating presents a compact cell structure with Ni,Cu,P elements evenly distributed.With the changing of Cu and P mass fraction,the coating structure consists of crystalline,mixed crystalline and amorphous states respectively.The crystalline coating has the highest hardness and best bonding strength,and the corrosion resistance of the amorphous coating is best.
