Abstract
The utility model relates to a reclaimed material zinc alloy surface coating structure which sequentially comprises a reclaimed material zinc alloy surface, an alkaline copper plating layer, a bright copper plating layer and a nickel plating layer from inside to outside. The reclaimed material zinc alloy surface coating structure provided by the utility model can be well applied to the reclaimed material zinc alloy surface with high impurity content, and reduce the visible flaws on the plated surface.
Description
Technical field
The utility model belongs to metal material surface coating technology field, relates in particular to a kind of reworked material zinc alloy surface coating structure.
Background technology
The reworked material zinc alloy is meant the zinc alloy that contains a large amount of impurity, and after die cast, the reworked material zinc alloy often has in electroplating process and a lot of surface spotses occurs; This is directly at reworked material zinc alloy surface Direct Electroplating bright plating copper because of prior art; Bright plating copper is also claimed the acid copper plating, is characterized in that electroplating velocity is fast, and light property is good; Shortcoming is because reaction is violent; The flaw position of reworked material zinc alloy surface is difficult to cover, and the flaw position deepened the degree of depth after receiving the acid electroplating corrosion on the contrary, makes flaw seem more obvious; Therefore, the reworked material zinc alloy is often because galvanized reason can not be applied in the occasion that electroplating quality is had relatively high expectations.
This shows that above-mentioned existing reworked material zinc alloy surface coating structure still has many defectives, and demands urgently improving.
Because the defective that above-mentioned existing reworked material zinc alloy surface coating structure exists; The design people is based on being engaged in this type of product design manufacturing for many years; Long-pending have abundant practical experience and expertise, actively studies innovation, in the hope of founding a kind of reworked material zinc alloy surface coating structure that improves molding structure; Can improve the general molding structure of existing reworked material zinc alloy surface coating on the market, make it have more competitiveness.Through constantly research, design, and after studying sample and improvement repeatedly, found out the utility model of true tool practical value finally.
The utility model content
The utility model technical problem underlying to be solved is; Overcome the defective that existing reworked material zinc alloy surface coating structure exists; And a kind of reworked material zinc alloy surface coating structure of novel texture is provided; Overcome existing reworked material zinc alloy and in electroplating process, often had the defective that a lot of surface spotses occurs, improved the quality of reworked material zinc alloy surface coating structure.
The utility model solves its technical problem underlying and adopts following technical scheme to realize.According to the reworked material zinc alloy surface coating structure that the utility model proposes, this structure comprises the reworked material zinc alloy surface from inside to outside successively, alkaline electro copper facing layer, bright plating copper layer and electroless nickel layer.
The utility model solves its technical problem and can also adopt following technical measures further to realize.
Before the thickness of described alkaline electro copper facing layer be 5 microns to 10 microns.
Before the scope of profile arithmetic average error Ra of surfaceness of described alkaline electro copper facing layer be 1 micron to 2 microns.
Before the thickness of described bright plating copper layer be 40 microns to 70 microns.
Before the thickness of described electroless nickel layer be 5 microns to 25 microns.
The utility model compared with prior art has tangible advantage and beneficial effect.Can know by above technical scheme; The utility model is owing to adopt technique scheme; The scope of the profile arithmetic average error Ra of the surfaceness of alkaline electro copper facing layer is 1 micron to 2 microns; Facts have proved that this surfaceness can guarantee the actual area that is in contact with one another of alkaline electro copper facing layer and bright plating copper layer; Can satisfy two-layer between the bonded needs, the roughness of the layer of alkaline electro copper facing simultaneously is close with the size of the flaw of reworked material zinc alloy surface, can cover well the flaw of reworked material zinc alloy surface; Alkaline electro copper facing layer has thickness of coating and increases slow characteristics; After increasing, thickness can fill the flaw position of reworked material surface of zinc alloy piece well; And the flaw position of reworked material surface of zinc alloy piece also is not easy to be increased the degree of depth by the basic plating corrosion; Simultaneously thickness reaches 40 microns to 70 microns bright plating copper layer and can the uneven surface of alkaline electro copper facing layer be covered well; Realize the effect that light is smooth, the reworked material zinc alloy surface coating structure of producing like this reaches the high quality requirement.
Above-mentioned explanation is merely the general introduction partly of the utility model technical scheme characteristic; For making the professional and technical personnel can more know the technique means of understanding the utility model; And can implement according to the content of specification sheets, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.
The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the sectional view of the utility model reworked material zinc alloy surface coating structure.
Among the figure, reworked material zinc alloy surface 1, alkaline electro copper facing layer 2, bright plating copper layer 3, electroless nickel layer 4.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to its embodiment, structure, characteristic and the effect thereof that proposes according to the utility model, specify as after.
See also shown in Figure 1; The reworked material zinc alloy surface coating structure of the utility model; This structure comprises reworked material zinc alloy surface 1, alkaline electro copper facing layer 2, bright plating copper layer 3 and electroless nickel layer 4 from inside to outside successively; The thickness of alkaline electro copper facing layer 2 is 5 microns to 10 microns; The scope of the profile arithmetic average error Ra of the surfaceness of alkaline electro copper facing layer 2 is 1 micron to 2 microns, and the thickness of bright plating copper layer 3 is 40 microns to 70 microns, and the thickness of electroless nickel layer 4 is 5 microns to 25 microns.
The utility model is owing to adopt technique scheme; Adopt the suitable alkaline electro copper facing layer of surfaceness; Alkaline electro copper facing layer has thickness of coating and increases slow characteristics; Can fill the flaw position of reworked material surface of zinc alloy piece after thickness increases well, and the flaw position of reworked material surface of zinc alloy piece is not easy also to be increased the degree of depth by the basic plating corrosion, the reworked material zinc alloy surface coating structure of producing like this reaches the high quality requirement.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
