Bright nickel plating method and control method of bright nickel plating film.

摘要

To provide a bright nickel plating method capable of forming a bright nickel plating film excellent in high corrosion resistance and high hardness and in which the elution of nickel is suppressed. The present invention relates to a bright nickel plating method in which an object to be plated is brought into contact with a bright nickel plating solution containing a water-soluble nickel compound, a primary brightener, a secondary brightener, and a potential regulator. The content of the primary brightener in the bright nickel plating solution is 0.1 to 2.0 g / L, and (2) the content of the secondary brightener in the bright nickel plating solution is 0.01 It is -0.5 g / L and (3) Content of the said potential regulator in the said bright nickel plating solution is 0.25-5.0 g / L, The bright nickel plating method characterized by the above-mentioned. 【Selection chart】 None
