摘　　要：介绍了一种以四氯金酸为主盐,由海因衍生物与亚硫酸盐复合体系构成的无氰镀金液,微观结构表征、电流效率测试、赫尔槽试验、中性盐雾试验等分析证实该镀液高效、稳定、环保,镀层外观及组织结构优于传统有氰镀金工艺。A cyanide-free gold plating bath based on tetrachloroauric(III)acid with the combination of hydantoin derivative and sulfite was introduced.The results of microstructure characterization,current efficiency testing,Hull cell test,neutral salt spray test,etc.confirmed that the multicomponent bath is highly efficient,stable,and environmentally friendly.The coatings obtained from the bath have better appearance and microstructure than that prepared from the traditional cyanidecontaining gold plating process.
