摘　　要：研究了采用浸锌-锡合金与预镀镍相结合的方法,在铝及其合金表面形成一层中间层再电镀光亮锡-铅合金工艺。介绍了铝及其合金制件的脱脂、碱蚀、出光及预镀等预处理工艺和配方,探讨了浸锌-镍合金溶液的配制、温度及时间对镀层性能的影响。结果表明,该工艺所获得的镀层结晶细致、光亮、焊接性能高、结合力强。The technology of the bright Sn-Pb alloy electroplating on aluminum and aluminum alloy with the pretreatment method of zinc-nickel immersion plating and nickel pre-electroplating was studied. An intermediate layer was formed by the pretreatment method. The process and solution of degrease, alkali erosion, brightening pretreatment and pre-electroplating were introduced. The effect of zinc-nickel immersion plating solution, temperature and plating time on the coating properties was discussed. The results show that the coating is of good crystal morphology,good adhesion and weldability.
