Abstract
When the electrodeposition of nickel is carried out in the presence of sulphur, it is desirable to control the content and the distribution of the sulphur in the deposited nickel. Sulphur-bearing nickel is deposited onto a multiplicity of cathodes (12) in an electrolytic cell. The electrolyte contains nickel ions, chloride ions, and at least one thiocyanate compound. To prevent oxidation of the thiocyanate ions by the chlorine gas generated at the anode (11), the chlorine is almost completely excluded from the cathode compartment by providing a flow of electrolyte from the cathode (12) to the anode (11) and by continuously removing chlorine and chlorine-containing electrolyte from the anode through a manifold (26). A weir (14) prevents back flow.
