摘要：提出了一种基于氯化钾镀锌体系的锌铁(钒)合金电镀溶液，其组成及工艺条件为：氯化锌80g/L，氯化钾240 g／L，硼酸30 g/L，R·G-618光亮剂18 mL／L，R·G-618配位剂60 mL／L，温度l5～35℃，pH 4．5，阴极电流密度0．5。3．0A／dm2。简述了所用添加剂的主要成分及作用。采用扫描电镜和x射线衍射分析了镀层的形貌和织构。在质量分数为3％的NaCl溶液的极化曲线测量和中性盐雾试验结果表明，锌铁(钒)合金镀层的耐蚀性比纯锌镀层更优异。 关键词：锌铁(钒)合金；电镀；添加剂；形貌；织构；耐蚀性 中图分类号：TQl53．2 文献标志码：A 文章编号：1004-227X(200g)0g-0010-04 Electroplating of zinc-iron(vanadium) alloy in potassium chloride electrolyte／／ZHOU Chang-hong*，WU Ming wei．JIANG Sheng Abstract：A Zn-Fe(V)alloy electroplating bath was developed based on the potassium chloride Zn plating electrolyte．The bath composition and process conditions are as follows：ZnCl2 80 g／L，KCl 240 g／L，H3803 30 g／L，R·G-618 brightening agent l 8 mL／L．R·G一618 complexing agent 60 mL／L。temperature l 5．35℃．pH 4．5 and cathodic current density 0．5-3．0 A／dm2．The main components and roles of the additives in potassium chloride electrolyte were in仃oduced．The deposit morphology and texture were analyzed by scanning electron microscopy and X-ray diffraction．The results of polarization curve measurement in a 3％(mass fraction)NaCl solution and neutral salt spray test showed that the Zn-Fe(V)alloy deposit has a superior corrosion resistance to pure Zn deposit． Keywords：zinc-iron(vanadium)alloy；electroplating；additive；morphology；texture；corrosion resistance First．author'S address：Wuhan Aobang Surface Technique C0．，Ltd．，Wuhan 430023，China
