| 中文摘要: |
| 为了研究希夫碱光亮剂DL01,DL02,DL03及添加剂Co(BF4)2在电镀时的电化学行为,采用线性电位扫描测定了氟硼酸盐光亮镀锡溶液中加入各种新型添加剂后的极化曲线。结果表明,在含DL01或DL03的氟硼酸盐镀液中,Sn2+的还原峰电位分别为- 0.230 V和- 0.320 V;在含DL01,DL03及少量Co(BF4)2的氟硼酸镀锡溶液中,Sn-Co共沉积峰电位为- 0.210 V;Co(BF4)2促进了Sn2+的沉积,Sn-Co的共析是协同共沉积。 |
| 英文摘要: |
| In order to explore the electrochemical behavior of Schiff base brighteners(DL01, DL02, DL03)and Co(BF4)2in plating, polarization curves in fluoroborate plating bright electroplating baths with additives by linear potential sweep was determined. The Sn2+ reduced peak potential in the bath with DL01, DL03 was- 0.230 V and- 0.320 V; The Sn-Co co-deposit peak potential was- 0.210 V in the bath with DL01, DL03 and a little Co(BF4)2. The fact showed that Co2+ accelerated Sn2+ deposit. The Sn-Co co-deposit was synergistic co-deposit. |
