Abstract
The utility model relates to a kind of aluminum alloy surface coating structure adopting new material, and this structure comprises aluminum alloy surface from inside to outside successively, electroless nickel layer, electroless nickel layer, nickel-phosphorus alloy functionally gradient deposit and nanocrystalline chromium-nickel alloy coating.The utility model adopts the aluminum alloy surface coating structure of new material aluminum alloy surface can be covered completely, simultaneously by controlling the various parameters such as the formula of electroplate liquid, the thickness of accurate each coating of control, especially adopt new material coating, make the utility model adopt the aluminum alloy surface coating structure of new material to have shiny appearance, wear-resisting, corrosion resistant effect.
Description
Technical field
The utility model belongs to metal material surface protection and furnishing fields, particularly relates to a kind of aluminum alloy surface coating structure adopting new material.
Background technology
Increasing electronic product constructional appearance part adopts aluminum alloy material, but plating on aluminium alloy easily causes the wearing and tearing of coating and comes off, and simultaneously due to the difference of material heat expansion, also can cause coming off of coating.
As can be seen here, above-mentioned existing aluminum 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 aluminum alloy surface coating structure overcoming existing employing new material exists, and a kind of aluminum alloy surface coating structure of employing new material of new structure is provided, overcome the defect of existing aluminum alloy surface coating structure, improve the quality of aluminum alloy surface coating structure.
The utility model solves its technical problem underlying and realizes by the following technical solutions.According to a kind of aluminum alloy surface coating structure adopting new material that the utility model proposes, this structure comprises aluminum alloy surface from inside to outside successively, electroless nickel layer, electroless nickel layer, nickel-phosphorus alloy functionally gradient deposit 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 electroless nickel layer is 2 microns to 3 microns.
The scope of the profile arithmetic average error Ra of the surface roughness of front described electroless nickel layer is 0.1 micron to 0.3 micron.
The thickness of front described electroless nickel layer is 3 microns to 6 microns.
The thickness of front described nickel-phosphorus alloy functionally gradient deposit is 20 microns to 80 microns.
The thickness of front described nanocrystalline chromium-nickel alloy coating is 10 microns to 40 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 electroless nickel layer is 0.1 micron to 0.3 micron, facts have proved that this surface roughness can ensure the actual area that contacts with each other of electroless nickel layer and electroless nickel layer, can meet two-layer between combine needs, the roughness of electroless nickel layer brings adverse effect also can not to the planarization of electroless nickel layer simultaneously, in addition chemical nickel plating and electronickelling are combined, the region that electroless nickel layer does not cover completely can be filled by electroless nickel layer well, adopt the thickness ratio of above-mentioned each layer simultaneously, the aluminum alloy surface coating structure of the employing new material produced like this reaches the high-quality requirement covered completely, there is shiny appearance simultaneously, wear-resisting, corrosion resistant effect.The phosphorus content gradient that the nickel-phosphorus alloy functionally gradient deposit prepared has and the distribution of thermal coefficient of expansion gradient can alleviate the thermal stress issues that coating causes because thermal coefficient of expansion does not mate with contact layer effectively, nickel-phosphorus alloy functionally gradient deposit dynamically can change electroplating voltage and realize in electroplating process, it is a kind of new coating material, by the graded of phosphorus content, progressively realize being changed by the gradient of crystal to amorphous, and the adaptability of the lattice surface thermal deformation of non-crystalline material improves, can effectively reduce the thermal stress caused because thermal coefficient of expansion does not mate, avoid the fatigue cracking of coating.Nanocrystalline chromium-nickel alloy coating light is smooth to compact, strong with nickel-phosphorus alloy functionally gradient deposit adhesion, and aerial wearability and excellent corrosion resistance, be applicable to the needs of electronic product constructional appearance 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.
