Abstract
The invention discloses an auxiliary anode for use in acid zinc-nickel alloy electroplating. The auxiliary anode comprises nickel (1), a base (2), insulating glue (3) and a lead (4), wherein the nickel (1) is connected to one end of the base (2); the other end of the base (2) is connected with the lead (4); the exposed surface of the base (2) and the root of the nickel (1) are coated with the insulating glue (3). The auxiliary anode has the beneficial effects that the problems of the auxiliary anode for use in acid zinc-nickel alloy electroplating are solved, and a clad layer can be obtained on the low-current-density area of a workpiece.
Description
Technical field
The present invention relates to electroplate and apparatus field, is specifically a kind of supplementary anode for acidic zinc Nickel alloy electroplating.
Background technology
Plating is a kind of process for treating surface that utilizes principles of electro-deposition to obtain coating.In electroplating process, the workpiece being plated, as negative electrode, treats that the dissolving parts of metal refining are as anode, and negative electrode and anode are dipped into and comprise in the electrolytic solution for the treatment of metal refining ion.Apply electric current, make metal ion electrolytic deposition at workpiece surface.
Irregular due to workpiece shape, just has the high district of current density and the low district of current density at workpiece surface.The high district of current density can obtain thicker galvanization coating, and can be thin or there is no coating completely in the thickness of coating in the low district of current density.In general, the way that solves the low district of current density coating deposition problems is that supplementary anode is set, and supplementary anode is deep into low current density district, artificially increases the current density in this region, makes it obtain coating.
The patent of report supplementary anode has a lot, but is all to focus in the structure design of supplementary anode substantially, and actually rare about the report of auxiliary anode material, and is all the insoluble auxiliary anode material of report.As patent CN101542023B has reported the supplementary anode of electroplating as wheel with titanium anode (being coated with iridium oxide/tantalum on titanium).Patent CN100580152C has reported the supplementary anode of electroplating as automobile tail pipe with stainless steel and terne metal.
Acidic zinc Nickel alloy electroplating is a kind of electroplating technology that development in recent years is got up.Patent CN1291068C has reported that the component of acidic zinc boron-tungsten-iron-nickel alloy electroplating is roughly as follows:
In the known acidic zinc boron-tungsten-iron-nickel alloy electroplating of above table, contain a large amount of chlorions.As everyone knows, in the environment of stainless steel under chlorion exists, corrode very fast, and if the supplementary anode using stainless steel as acid zinc-nickel plating, its dissolution rate can be faster, and can introduce a large amount of iron contaminations to electroplate liquid.And about titanium anode, patent US5162079 mentions titanium anode under the environment of high chloride ion, anode surface can be separated out chlorine, and chlorine is toxic gas.About terne metal anode, periodical literature reported, in similar acid zinc plating electroplate liquid, lead-tin anode can dissolve, thereby causes containing in coating plumbous impurity.So above-mentioned auxiliary anode material is all not suitable for being used in acidic zinc nickel alloy electricity and plates.
Summary of the invention
Technical problem to be solved by this invention is the defect that overcomes prior art, has proposed a kind of supplementary anode for acidic zinc Nickel alloy electroplating.
The technical solution adopted for the present invention to solve the technical problems: be a kind of supplementary anode for acidic zinc Nickel alloy electroplating, comprise nickel, pedestal, insulation paste and wire.Nickel is connected to pedestal one end, and the pedestal the other end connects wire.On the exposed surface of pedestal and nickel root, coat insulation paste.
The invention has the beneficial effects as follows: solved the supplementary anode problem of acidic zinc Nickel alloy electroplating, can make the low district of current density on workpiece obtain coating.
