Method of suppressing increase in zinc concentration of plating solution and method of manufacturing zinc-based plating member

摘要

PROBLEM TO BE SOLVED: To provide a zinc-based plating apparatus in which a zinc ion concentration is unlikely to increase when the anode is soluble, and a method for manufacturing a zinc-based plating member using such a zinc-based plating apparatus. SOLUTION: A plating tank 10 capable of accommodating a plating solution PE, a first diaphragm tank 20 capable of accommodating a first electrolytic solution and having a first diaphragm 21 including a first ion exchange membrane, and the above when in use. A cathode holding member 30 for cathodic electrolysis of a member to be plated that comes into contact with the plating solution inside the plating tank, and a soluble zinc-containing member 41 that comes into contact with the first electrolytic solution inside the first diaphragm tank during use. A first anode holding member 40 for anodic electrolysis is provided so that the first electrolytic solution comes into contact with one surface of the first diaphragm and the plating solution comes into contact with the other surface of the first diaphragm during use. In addition, the zinc-based plating apparatus 100 is characterized in that the first diaphragm tank is arranged. [Selection diagram] Fig. 1
