    摘要: The object of the present invention is to provide an electroplating method that enables the high-speed treatment of articles to be plated that was difficult to achieve with the conventional tin-zinc electroplating. The present invention provides a method for electroplating with a tin-zinc alloy that is performed under the following conditions: plating bath temperature 30 to 90°C, plating bath stirring rate 5 to 300 m/min, and cathode current density 5 to 200 A/dm 2 . Preferably, in the tin-zinc alloy plating bath, the divalent tin ion concentration is 1 to 100 g/L and the zinc ion concentration is 0.2 to 80 g/L.
