PROCESS OF PREPARATION OF ELECTROLYTE FOR DEPOSITION OF METAL NICKEL ( VERSIONS )

摘要

FIELD: electrolytic deposition of nickel coats. SUBSTANCE: in correspondence with invention sulfate-chloride or sulfamine electrolytes widely used in industry are diluted with distilled ( demineralized ) water in proportion 1: 1-1: 1.3, methane-sulfane acid or methane-sulfane nickel in the amount of 120-200 g/l is added and general concentration of cations of nickel in solution at level of 49-100 g/l is ensured. Spent sulfate-chloride or sulfamine electrolytes are taken in the capacity of starting electrolytes. Required concentration of cations of nickel in solution can be obtained by way of electrolytic dissolution of nickel anodes in it. EFFECT: enhanced productivity of process of deposition of nickel coats with provision of their high quality and reduced cost. 6 cl
