| Abstract: |
| 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. |
