Embodiment Construction

[0014] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] figure 1 Shown is the first embodiment of the present invention applied to the anode of alkaline zinc-nickel alloy electroplating. The anode applied to the alkaline zinc-nickel alloy electroplating includes a plate-shaped zinc material 1, and can increase and decrease the zinc material 1 contacting the electroplating solution when the anode applied to the alkaline zinc-nickel alloy electroplating is placed in the electroplating solution Area barriers. The barrier device is made of a material with an electrode potential higher than that of zinc. In this embodiment, all structures of the barrier device are made of carbon steel.

[0016] In the electroplating process, since the electrode potential of the material of the barrier device, that is, carbon steel, is higher than that ...

Abstract

The invention relates to an electroplating anode, and in particular relates to an anode used for electroplating of an alkaline zinc-nickel alloy. The anode comprises a zinc material and a blocking device, wherein the blocking device can be used for increasing or reducing the contact area between the zinc material and an electroplating solution when the anode used for electroplating of the alkaline zinc-nickel alloy is placed in the electroplating solution, and the blocking device is prepared from a material of which the electrode potential is higher than that of zinc. When performing electroplating by adopting the anode used for electroplating of the alkaline zinc-nickel alloy, the relative stability of the zinc ion concentration in the electroplating solution can be ensured, and the management difficulty of the electroplating process can not be improved.

Description

technical field [0001] The invention relates to an electroplating anode, in particular to an anode applied to alkaline zinc-nickel alloy electroplating. Background technique [0002] With the rapid development of science and technology and modern industry, zinc coating can no longer meet people's requirements for high corrosion resistance, and the application of electroplated zinc-based alloys is becoming more and more extensive. Among zinc-based alloys, zinc-nickel alloys have high corrosion resistance (3 to 6 times that of zinc coatings), and are an excellent protective and decorative coating, suitable for use in harsh industrial environments and harsh marine environments. It is also widely used in auto parts, especially for high-strength steel and spring steel. [0003] For the alkaline zinc-nickel alloy electroplating process, since the current efficiency of zinc anode dissolution is much greater than that of cathode zinc precipitation, the concentration of zinc ions in...
