    摘要:提出了一種基于氯化鉀鍍鋅體系的鋅鐵(釩)合金電鍍溶液,其組成及工藝條件為:氯化鋅80g/L,氯化鉀240 g/L,硼酸30 g/L,R·G-618光亮劑18 mL/L,R·G-618配位劑60 mL/L,溫度l5~35℃,pH 4.5,陰極電流密度0.5。3.0A/dm2。簡述了所用添加劑的主要成分及作用。采用掃描電鏡和x射線衍射分析了鍍層的形貌和織構。在質量分數為3%的NaCl溶液的極化曲線測量和中性鹽霧試驗結果表明,鋅鐵(釩)合金鍍層的耐蝕性比純鋅鍍層更優異。

    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.
