摘　　要：研究搅拌方式对Ni-Fe合金镀层显微组织形貌、铁的质量分数的影响,最终获得最佳工艺下的搅拌方式。采用扫描电子显微镜观察镀层微观形貌,X-ray衍射仪分析镀层相结构,能谱仪对镀层成分进行分析。结果表明:搅拌方式对镀层成分及显微形貌有较大影响。静止电沉积时镀层中铁的质量分数最低为38.82%;采用空气搅拌时铁的质量分数最高为55.06%,加强搅拌可增加镀层中铁的质量分数。无搅拌或搅拌不均匀时,镀层会出现针孔、裂纹、结晶不致密等疵病;搅拌均匀时,镀层细致,排列致密。The effects of stirring methods on microstrueture and mass fraction of iron of Ni-Fe alloy coating are investigated, obtaining a stirring way suitable for optimal processing conditions. The microstucture, phase structure and component of the coating are characterized by SEM, XRD, EDS. The results show that stirring methods have more effect on the content and microsturcture of the coatings. The lowest mass fraction of iron is 38. 82% when stirring is not used while the highest mass fraction of iron can reach 55.06% when air agitation is used. Mass fraction of iron will increase with strong stirring. Pinholes, fissures, ineompact crystallization, etc. will appear in the coating without stirring or with uneven stirring. The coating will be uniform and compactly arranged when uniform stirring is adopted.
