摘　　要：研制了一种高性能环保型碱性锌酸盐镀锌添加剂CZ,采用电化学测试、扫描电镜分析及EDAX能谱分析等手段进行了镀层性能检测,并将其与传统添加剂性能进行了比较。结果表明,该添加剂具有光亮电流范围广、分散能力佳、深镀能力好等优点,所得镀层脆性低,二次加工性好。A novel environmentally acceptable additive for zinc electroplating in a non-cyanide alkaline zincate bath was developed. The performance of the additive was investigated and compared to that of convention additives making use of electrochemical testing, scanning electron microscopic observation, and energy dispersive X-ray analysis. It was found that the newly developed additive had a broad current density range for bright electroplating, good dispersion capability, and good throwing power. The corresponding electroplated Zn coating prepared in the presence of the newly developed additive had a small brittleness and good re-machining performance.
