Abstract
The utility model relates to a panel of a cathode composite coating structure, wherein the coating structure comprises a base plate layer, a rare metal layer is compounded on the surface of the base plate layer, an active coating is compounded on the surface of the rare metal layer, the rare metal layer is used for firmly combing the base plate layer and the active coating. The rare metal layer is a ruthenium, or iridium, or platinum powder metal layer, the active coating is a compound rare metal layer which is a powder metal layer, the rare metal layer and the compound rare metal layer are combined with the base plate layer through the electric plating mode. As a compound coating is electroplated on the surface of a base plate in the panel of the cathode composite coating structure, the connection between the coating and the base plate in the panel is more firm, the coating and the base plate are not easy to drop, the surface of the panel is smooth and hard, and the compound plate has simple processing process and low cost, and improves the quality of the panel of the cathode composite coating structure.
Description
Technical field
The utility model relates to the structure of composite sheet, is specifically related to a kind of panel of negative electrode composite coating structure.
Background technology
Use in the cathode in existing electrolysis, general just by apply the precious metal oxide coating of one deck at negative electrode (Ni) substrate surface, in order to reduce cathode potential, but combining between metal oxide containing precious metals top coat and base material is not very fine and close, very firm, thereby panel is to make the cathode degradation in the impact that use runs into reversible circulation, coating shedding, fall flat work-ing life, therefore is necessary precious metal oxide coating structure and technology that existing negative electrode (Ni) substrate surface applies are improved.
The utility model content
The purpose of this utility model is to overcome defective of the prior art, designs a kind of panel of negative electrode composite coating structure, combines firmly difficult drop-off, its smooth surface, hard between the coating in this panel and the substrate.
For achieving the above object, the technical solution of the utility model is to adopt a kind of panel of negative electrode composite coating structure, and described coating structure comprises that the described plaque layer surface recombination of plaque layer has layer of precious metal, in the surface recombination of described layer of precious metal activated coating is arranged; Described layer of precious metal is used for described plaque layer and firm the combining of described activated coating.
Wherein, described layer of precious metal is the powder attitude metal level of ruthenium or iridium or platinum.
Wherein, described activated coating is multiple layer of precious metal, and described multiple layer of precious metal is a powder attitude metal level.
Wherein, described layer of precious metal, multiple layer of precious metal combine by galvanized mode and described plaque layer.
Wherein, described plating is in conjunction with comprising that cold plating or heat invades.
Advantage of the present utility model and beneficial effect are: because a kind of panel of negative electrode composite coating structure has adopted at the electroplating surface of substrate composite deposite, make and combine firmly between coating and the substrate in this panel, difficult drop-off, its smooth surface, hard, and this composition board complete processing is simple, with low cost, improved the quality of negative electrode composite coating structure panel simultaneously.
Description of drawings
Fig. 1 is the panel construction synoptic diagram of the utility model negative electrode composite coating structure.
Among the figure: 1, plaque layer; 2, layer of precious metal; 3, activated coating.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, the concrete technical scheme of implementing of the utility model is:
A kind of panel of negative electrode composite coating structure, described coating structure comprise that plaque layer 1 described plaque layer 1 surface recombination has layer of precious metal 2, in the surface recombination of described layer of precious metal 2 activated coating 3 are arranged; Described layer of precious metal 2 is used for described plaque layer 1 and described activated coating 3 firm combining.
On the basis of embodiment 1, the powder attitude metal level that layer of precious metal 2 described in the utility model is ruthenium or iridium or platinum.
On the basis of embodiment 2, activated coating 3 described in the utility model is multiple layer of precious metal, and described multiple layer of precious metal is a powder attitude metal level.
Embodiment 4
On the basis of embodiment 3, layer of precious metal 2 described in the utility model, multiple layer of precious metal combine by galvanized mode and described plaque layer 1.
Embodiment 5
On the basis of embodiment 4, plating described in the utility model is in conjunction with comprising that cold plating or heat invades.
The utility model is by adding single noble coatings of planting of the densification that is coated with one deck ruthenium Ru or iridium Ir or platinum Pt in addition between Ni base material and coating, make between the multiple precious metal oxidation spy coating on base material and surface and form good binding, reaches the effect of anti-reversible circulation.
Advantage of the present utility model is: because a kind of panel of negative electrode composite coating structure has adopted at the electroplating surface of substrate composite deposite, make and combine firmly between coating and the substrate in this panel, difficult drop-off, its smooth surface, hard, and this composition board complete processing is simple, with low cost, improved the quality of negative electrode composite coating structure panel simultaneously.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
