研究了锌镍合金钝化液组成及钝化处理工艺 ,通过对钝化液成分进行分析和钝化工艺的试验研究 ,采用能谱分析法和弱极化电流密度腐蚀试验方法对锌镍合金钝化膜性能进行了检测。试验结果表明 :本钝化液配方在pH值 1.0 0～ 1.4 5、钝化温度 35～ 5 5℃、钝化液Zn2 + ≤ 1.5g/L条件下 ,镍含量为 6%～ 17%的锌镍合金镀层可以获得优良的Zn Ni Cr钝化膜 ,钝化的锌镍合金镀层耐腐蚀性能是电镀锌层、热镀锌层的 4倍以上 The composition and passivation process of zinc-nickel alloy passivation solution were studied. Through the analysis of the passivation solution composition and the passivation process, the energy dispersive spectroscopy and weak polarization current density corrosion test were used to study the passivation of zinc-nickel alloy Film properties were tested. The results show that the passivation solution has the following properties: zinc (1.0% ~ 1.4%), passivation temperature 35 ~ 55 ℃, Zn2 + ≤ 1.5g / L, zinc with 6% ~ 17% Nickel alloy coating can get excellent Zn Ni Cr passivation film, passivation zinc-nickel alloy coating corrosion resistance is galvanized layer, hot dip galvanized layer more than 4 times
