中文摘要：
采用恒电流沉积方法和x射线能谱（EDS）技术，研究了碱性Zn—Ni合金的主要电沉积工艺参数对镀层组成的影响规律，获得了Ni含量稳定为（11-13）mass％的Zn—Ni合金镀层，证实了Zn—Ni合金的共沉积过程遵循异常共沉积机制。采用扫描电镜（SEM）、原子力显微镜（AFM）和x射线衍射仪（XRD）等对优化的Zn—Ni合金镀层进行了表征，发现镀层主要具有γ相（NiZn3）结构，其表面平整、致密、光亮；腐蚀测试表明Zn—Ni合金镀层具有优良的耐蚀性能。
英文摘要：
Zinc-nickel alloy coatings were electroplated from an alkaline electrolyte using direct current, the influences of principal technological parameters on the composition of zinc-nickel alloy coatings were studied using energy dispersive spectrometer （EDS）. The results show that the content of nickel in Zn-Ni deposits kept between 11% and 13% and the co-deposition of zinc and nickel behaved anomalously. The microstructure of the optimized deposition was characterized by scanning transmission electron microscope （SEM）, atomic force microscope （AFM） and X-ray diffractometer （XRD）, the results showed that the Zn-Ni deposits consisted mainly of the γ-phase（NiZn3） and the film was compact and fine-grained. Meanwhile, the Tafel plot measurements proved the coating had good corrosion resistance.
