Description
Technical field
The utility model belongs to metal material surface coating technology field, particularly relates to a kind of new zinc alloy surface plating structure adopting nano material.
Background technology
Often there is the defective products of about 10% because of depression flaw in electronic product surface structure part quality check process after plating, surface of zinc alloy piece with deep recess position requires that depressed area is plated layer and fills, prior art zinc alloy piece carries out the plating of simple bright plating copper, bright plating copper also claims acid copper to electroplate, be characterized in that electroplating velocity is fast, bright property is good, and shortcoming is difficult to make deep recess position be plated layer fill.Zinc alloy piece is as electronic product surface structure part simultaneously, and often adopt chromium to protect as outermost layer, but the bond strength of its wearability and lower floor is difficult to meet the increasing instructions for use of people, coating surface is easily worn and exposes bottom material.
As can be seen here, above-mentioned existing zinc alloy surface coating structure still has many defects, and is urgently improved.
Utility model content
Technical problem underlying to be solved in the utility model is, the defect that the new zinc alloy surface plating structure overcoming existing employing nano material exists, and a kind of new zinc alloy surface plating structure of employing nano material of new structure is provided, improve the quality of zinc alloy surface coating structure.
The utility model solves its technical problem underlying and realizes by the following technical solutions.According to the new zinc alloy surface plating structure of the employing nano material that the utility model proposes, this structure comprises zinc alloy surface from inside to outside successively, basic plating layers of copper, bright plating layers of copper and nanocrystalline chromium-nickel alloy coating.
The utility model solves its technical problem and following technical measures can also be adopted to realize further.
The thickness of front described basic plating layers of copper is 2 microns to 4 microns.
The scope of the profile arithmetic average error Ra of the surface roughness of front described basic plating layers of copper is 0.5 micron to 1 micron.
The thickness of front described bright plating layers of copper is 5 microns to 15 microns.
The thickness of front described nanocrystalline chromium-nickel alloy coating is 20 microns to 50 microns.
The utility model compared with prior art has obvious advantage and beneficial effect.From above technical scheme, the utility model is owing to adopting technique scheme, the scope of the profile arithmetic average error Ra of the surface roughness of basic plating layers of copper is 0.5 micron to 1 micron, facts have proved that this surface roughness can ensure the actual area that contacts with each other of basic plating layers of copper and bright plating layers of copper, can meet two-layer between the needs that combine, simultaneously the roughness of basic plating layers of copper bring adverse effect also can not to the planarization of bright plating layers of copper; Basic plating layers of copper has thickness of coating and increases slow feature, the deep recess portion faces of zinc alloy piece can be covered well, one deck bright plating layers of copper is covered outward again in basic plating layers of copper, reach the effect of light, adopt the thickness ratio of above-mentioned each layer simultaneously, the new zinc alloy surface plating structure of the employing nano material produced like this reaches high-quality requirement, has shiny appearance, wear-resisting, corrosion resistant effect simultaneously.Nanocrystalline chromium-nickel alloy coating light is smooth to compact, strong with bright plating layers of copper adhesion, and aerial wearability and excellent corrosion resistance, be applicable to the application of electronic product surface structure part.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model feature part, technological means of the present utility model is better understood for enabling professional and technical personnel, and can be implemented according to the content of description, coordinate accompanying drawing to be described in detail as follows with preferred embodiment of the present utility model below.
Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to according to its detailed description of the invention, structure, feature and the effect thereof that the utility model proposes, be described in detail as follows.
