【Abstract】 The electrolyte was compelled to form turbulent flow by using speed electroplating apparatus. The Zn-Ni alloy electro-deposition law in simple sulphate system under high current density was studied. The results indicated that Zn-Ni alloy electroplating is abnormal co-deposition. The content of nickel in the deposite increases with the increase of the ratio of Ni/Ni+Zn and the current density. It decreases with the increase of the fluid speed of electrolyte. On the above basis, the technology of high speed Zn-Ni alloy electroplating has been determined.更多还原
