摘　　要：该文给出一种电镀铋的碱性镀液配方,并由正交实验得到优化方案为:硝酸铋60 g/L,乙二胺四乙酸二钠(EDTA)90 g/L,5-磺基水杨酸120 g/L,酒石酸钾钠60 g/L,氯化钾60 g/L.分别讨论了铋质量浓度对镀液镀速的影响以及配位剂对阴极极化的影响.检测了铋镀层的表面粗糙度、微观形貌、附着强度等性能,结果表明:铋镀层表面均匀、平滑,结晶细致无裂纹,附着强度好,色泽光亮.The alkaline electroplating bath formulation of bismuth was developed.The optimal composition formula was obtained by an orthogonal method as follows：bismuth nitrate 60 g/L,disodium ethylene diamine tetraacetate（EDTA） 90 g/L,5-sulfosalicylic acid 120 g/L,potassium sodium tartrate 60 g/L,potassium chloride 60 g/L.The influence of bismuth content on the rate of bismuth coating and complexing agents on the impact of cathode polarization was investigated.The surface roughness,microstructure and adhesion strength of bismuth coating was detected.The result was that the bismuth coating had the features of fine and uniform grain,good smoothness,good adhesion and bright color.
