摘　　要：以二甲基海因衍生物、多元醇、硝基苯磺酸盐、苹果酸和亚硫酸盐组成开缸剂,聚乙烯亚胺、丁二酸和乳酸组成调色剂,苯基嘧啶、烷基嘧啶、吡啶衍生物和甜菜碱组成光亮剂,配制了适用于磷酸盐体系无氰镀金的复配添加剂。研究表明,该添加剂能大幅增强镀液的稳定性,降低镀层的孔隙率,提高镀层的光泽、硬度和耐蚀性。The multicomponent additives applied to cyanide-free gold electroplating in a phosphate bath were prepared.The make-up agent comprises dimethylhydantoin derivative,polyol,nitrobenzenesulfonate,and malic acid.The toner comprises poly(ethylene imine),succinic acid,and lactic acid.The brightener comprises phenylpyrimidine,alkylpyrimidine,pyridine derivative,and betaine.The experimental results showed that the application of the additives enhances the bath stability,reduces the porosity of gold coating,and improves its gloss,hardness,and corrosion resistance.
