摘　　要：研究了一种无铵弱酸性锌镍合金电镀工艺,并深入探讨了镀液的成分及工艺条件对镀层含镍量的影响,得到了镀层为γ相Ni5Zn21与δ相Ni3Zn22、且含镍量为13%的全光亮锌镍合金镀层,确定了电镀工艺规范。该镀层具有极好的耐高温性能及优良的耐腐蚀性。Ammonium-free weak acidic electroplating technology for Zn-Ni alloy was developed. The effects of the bath composition and processing condition on the nickel content in the plating were investigated, and the electroplating process criterion was established. As the results, it was feasible to prepare bright Zn-Ni alloy plating containing 13% Ni using the developed technology. The Zn-Ni alloy plating was composed of γ-Ni_5Zn_ 21 and δ-Ni_3Zn_ 22 phases. The Zn-Ni alloy plating had excellent high temperature resistance and corrosion resistance.
