Abstract
Some preliminary results of the effects of magnetic fields on high current efficiency electrodeposition of CR-FE alloys were reported previously (1). For the present experiments, high purity Ni cathodes and Pb anodes were used. The cathode current density was 0.25 amps/cm2 and the cathode and anode were positioned vertically and parallel to each other and to the horizontal magnetic field (B). Two series-wired water-jacketed electrolytic cells were used. One cell was located between the pole pieces of an electromagnet and the other was approximately 30 cm away. The plating time was 30 minutes for each experiment and the current efficiency varied from 51.8 to 53.9% for the deposits in Fig. A. The initial cell temperature was 40°C.
