摘要

Improvements introduced in a process for the electrodeposition of zinc, characterized the improvements by which they consist of effecting electrodeposition with a bright zinc electrolytic bath, free of cyanides, comprising an aqueous alkaline solution containing a source of zinc ions, a brightener, a heterocyclic compound selected from the group consisting of a 2-mercapto-pyridine or pyrimidine and a quaternized polymer condensate of an alkylene polyamine containing at least one tertiary amino group and an epibalohydrin, and in that said electrodeposition is carried out at a temperature comprised approximately 60 and 100º f (15.5 and 38º c) and at a current density of one to 200 amperes/ft2 (0 to 21.5 amperes/dm).
