Design of Electrolytic Cell for Continuous Electrodeposition of Iron-Nickel Alloy's Thin Film

As the results of several operations using various types and sizes of anode, thin film deposition of Fe-Ni alloys on fine copper wire was successful by using the electrolytic cell holding conical platinum ring anode as shown in Fig. 4. The electrolytic cell shown in Fig. 1 was used in the previous reports. However, it was clear that the current distribution in the above cell was more dense in the first half part (adjacent to lead-in) of fine cathode wire due to its high internal resistance. Then, many types of anode were devised such as cylindrical ring (30cm and 10cm in length), the anode having separated circuits for supplying uniform current density to each ring, conical anode (10cm in length), etc.
