中文摘要:
      目的 研究锌镍合金镀层的耐腐蚀性能。 方法 通过正交试验法,对锌镍合金电镀工艺进行优化,获得镀液配方。 通过中性盐雾试验评判优化后的锌镍合金镀层的耐腐蚀性能,并与镀锌层和镀镉层进行对比。 分析主盐、络合剂、pH 值、电流密度、温度等对镀层耐腐蚀性的影响。 结果 最优配方为:氧化锌 6 ~14 g/ L,硫酸镍 20 ~30 g/ L,氢氧化钠 100 ~140 g/ L,光亮剂 4 ~6 g/ L,络合剂 50 ~70 g/ L。 该配方获得的锌镍合金镀层在中性盐雾实验中,出白锈的时间可以达到 720 h 以上。 结论 锌镍合金镀层的耐腐蚀性优良,优于镀锌层和镀镉层。
英文摘要:
      Objective To study the corrosion resistance of Zn-Ni alloy coating. Methods By orthogonal test method, the Zn-Ni alloy electroplating technology was optimized, and the plating solution formula was obtained. The corrosion resistance of the optimized Zn-Ni alloy plating was evaluated by neutral salt spray test, and compared to those of the galvanized layer and cadmium plating layer. The influence of the main salt, complexing agent, pH value, current density and temperature on the coating corrosion resistance was analyzed. Results The optimal formula was: zinc oxide 6 ~14 g/ L, nickel sulfate 20 ~30 g/ L, sodium hydroxide 100 ~ 140 g/ L, brightener 4 ~6 g/ L, and complexing agent 50 ~70 g/ L. The Zn-Ni alloy coating obtained using this formula had a white rust occurrence time of more than 720 hours in the neutral salt spray test. Conclusion The Zn-Ni alloy coating had excellent corrosion resistance, superior to those of zinc and cadmium plating layer.
