摘　　要：通过扫描电镜（SEN）和X射线能谱（EDS）研究了在435℃下锌镍合金镀液中形成的锌渣微观形貌和相成分。结果表明，锌浴中Ni质量分数低于0．051％时，锌渣仅为单一含Ni的ξ相，锌浴中Ni质量分数在0．051％～0．093％范围内，锌渣为Г2和ξ两相共存，锌浴中Ni质量分数大于0．093％时，则锌渣仅为Г2相。出现Г2相时锌浴的临界成分点为0．010％Fe和0．051％Ni。The microstructure and phase composition of zinc dross formed in Zn-Ni alloy bath at 435 ℃ was studied by SEM and EDS. The results show that there is only single ξ phase containing Ni in zinc dross when Ni content in zinc bath is less than 0.051%. When Ni content in zinc bath is in the range of 0. 051% -0. 093%, there are Г2 and ξ twophase coexistence in zinc bath. When Ni content in zinc bath is more than 0.093%, there is only Г2 phase. The critical composition of zinc bath is 0.010% Fe and 0. 051% Ni when Г2 phase formed.
