In the practical application process, the inventor of the present utility model found through research: the magnesium-aluminum composite structure has an internal structure of a magnesium alloy layer and an aluminum alloy layer which are stacked, and the magnesium-aluminum composite structure can be applied to an electronic device as an appearance member (i.e., the magnesium-aluminum composite appearance member, such as the first housing 100) through surface treatment, so as to solve the problem of overweight of the housing of the electronic device at present.

Regarding the method for producing the magnesium aluminum composite exterior member from the magnesium aluminum composite structure, the following will be described in connection with the exemplary embodiments:

in this exemplary embodiment, the magnesium-aluminum composite structure as a raw material includes a magnesium alloy layer and an aluminum alloy layer that are stacked. The magnesium aluminum composite exterior member 100 as a target product includes a magnesium alloy base material layer 30, an aluminum alloy base material layer 10, an anodized layer 50, and a micro-arc oxidized layer 70; wherein the aluminum alloy substrate layer 10 is laminated on the magnesium alloy substrate layer 30; the anodic oxidation layer 50 covers the surface of the aluminum alloy substrate layer 10 facing away from the magnesium alloy substrate layer 30; the micro-arc oxidation layer 70 covers at least a portion of the surface of the magnesium alloy substrate layer 30 and the aluminum alloy substrate layer 10 exposed by the anodized layer 50 (as shown in fig. 2).

That is, it is necessary to obtain the target product by surface treatment of the raw material for application to the electronic device. At this time, the inventors of the present utility model found by study that: the key point of the surface treatment is that when the magnesium alloy layer is subjected to micro-arc oxidation treatment in alkaline electrolyte, the aluminum alloy layer is protected from corrosion; or when the aluminum alloy layer is anodized in the acid electrolyte, the magnesium alloy layer is protected from corrosion.

To this end, the inventors of the present utility model propose a method for manufacturing a magnesium aluminum composite exterior member 100: the proper shielding layer is flexibly adopted in the micro-arc oxidation or anodic oxidation treatment process to protect the corresponding alloy layer from being corroded by electrolyte, so that the anodic oxidation process for the aluminum alloy layer and the micro-arc oxidation process for the magnesium alloy layer are successfully completed, and the magnesium-aluminum composite appearance member 100 which can be applied to electronic equipment is obtained. The outer layer of the magnesium-aluminum composite appearance member 100 is an aluminum alloy layer with the surface subjected to anodic oxidation treatment, has an anodic oxidation appearance effect, and has high glossiness, various colors, metallic texture and strong corrosion resistance and wear resistance. The inner layer of the magnesium-aluminum composite appearance member 100 is a magnesium alloy layer with the surface subjected to micro-arc oxidation treatment, and the fracture of the magnesium alloy layer and the fracture of the aluminum alloy layer are subjected to micro-arc oxidation treatment, so that the magnesium alloy member has strong corrosion resistance and wear resistance.

That is, the magnesium-aluminum composite appearance member 100 prepared by the preparation method of the magnesium-aluminum composite appearance member 100 has both magnesium alloy micro-arc oxidation corrosion prevention and wear resistance effects and aluminum alloy anodic oxidation appearance texture, and is suitable for being applied to various electronic devices, such as: glasses, cell phones, tablet computers, televisions, displays, notebook computers, digital photo frames, personal digital assistants (Personal Digital Assistant, PDA), electronic book readers, MP3 (moving picture experts compression standard audio layer 3,Moving Picture Experts Group Audio Layer III) players, MP4 (moving picture experts compression standard audio layer 4,Moving Picture Experts Group Audio Layer IV) players, wearable devices, navigators, palm game consoles, virtual reality devices (VR), augmented reality devices (AR), and the like.

Thus, the problem that the existing aluminum alloy appearance member is heavier and the magnesium alloy appearance member is difficult to obtain the appearance texture of the aluminum alloy appearance member is solved, and the problem that the existing appearance member based on the magnesium aluminum composite structure is difficult to treat the surface is also solved.

Specifically, compared with the related art, the prepared target product-magnesium-aluminum composite appearance member 100 is based on the magnesium alloy substrate layer 30 and the aluminum alloy substrate layer 10 which are stacked, and the surface of the aluminum alloy substrate layer 10, which is far away from the magnesium alloy substrate layer 30, is covered with the anodic oxidation layer 50, so that the anodic oxidation appearance texture of the aluminum alloy appearance member is comparable; meanwhile, by covering the micro-arc oxidation layer 70 on at least part of the surfaces of the magnesium alloy base material layer 30 and the aluminum alloy base material layer 10 exposed by the anodic oxidation layer 50, micro-arc oxidation corrosion resistance comparable to that of the magnesium alloy exterior member is also obtained. Compared with the traditional aluminum alloy appearance component, the lightweight advantage is obtained; compared with the traditional magnesium alloy appearance component, the excellent appearance effect of the aluminum alloy appearance component is obtained. The magnesium-aluminum composite appearance member 100 is applied to a housing assembly of an electronic device, so that the problem of overweight of the housing of the electronic device at present can be solved.

In addition, the preparation method of the magnesium-aluminum composite appearance member 100 is also beneficial to realizing industrialized mass production, has the advantages of mature process, perfect industrial chain, low processing cost, stable quality, low equipment investment and the like, and is particularly suitable for miniaturized consumer electronic products such as mobile phones, notebook computers, AR, VR, intelligent watches and the like which have strong demands on light weight and appearance texture.

As shown in fig. 4, a flow chart of a method for preparing the magnesium aluminum composite exterior member 100 includes the following steps:

step S100, providing a component rough blank (namely the magnesium-aluminum composite structure); wherein, the component rough blank includes a magnesium alloy layer and an aluminum alloy layer that are stacked.

Specifically, when the provided member blank satisfies the requirement of the subsequent process, the subsequent process may be directly performed. Otherwise, the step of providing a component blank may further comprise: (1) Cleaning the component rough blank to remove oil stains and attached impurities on the surface; (2) And (3) carrying out mechanical polishing treatment on the surface of the aluminum alloy layer, namely polishing the surface by using abrasive paper from coarse to fine in sequence, and polishing the surface by using silk to remove the defects of scratches, pits and the like on the surface, thereby improving the surface glossiness.

Step S200, performing a first masking treatment on the member blank to attach a first masking layer on the aluminum alloy layer.

Specifically, in order to secure the shielding effect, a plurality of spraying, coating, or the like processes may be employed. The low-temperature drying process can be inserted to ensure the drying of each layer and obtain certain adhesive force, so that the whole first shielding layer can obtain good adhesive force, and better shielding effect can be realized. The existence of the first shielding layer can ensure that the surface of the aluminum alloy layer is not corroded by alkaline electrolyte in the micro-arc oxidation process.

And step S300, performing micro-arc oxidation treatment on the component blank to form a micro-arc oxidation layer 70 on the surface of the component blank exposed by the first shielding layer.

Specifically, the micro-arc oxidation treatment can be performed by adopting a conventional magnesium alloy micro-arc oxidation process: the electrolyte composition can be common sodium hydroxide system, silicate system, phosphate system, etc., the micro-arc oxidation voltage can be controlled between 300V and 550V, and the current density can be controlled at 1.2A/dm ² ～4.0A/dm ² The oxidation time can be controlled between 10min and 30min. In the process, the surface of the aluminum alloy layer is not directly contacted with electrolyte due to the protection of the first shielding layer, so that chemical reaction is not generated.

Step S400, performing a second masking treatment on the component blank to attach a second masking layer on the micro-arc oxide layer 70, and removing the first masking layer.

Specifically, in order to secure the shielding effect, a plurality of spraying, coating, or the like processes may be employed. The low-temperature drying process can be inserted to ensure the drying of each layer and obtain certain adhesive force, so that the second shielding layer integrally obtains good adhesive force, and better shielding effect is realized. The presence of the second masking layer may ensure that the micro-arc oxidation layer 70 is not corroded by the acid electrolyte during the anodic oxidation process. As for the removal of the first shielding layer, it may be achieved by, for example, mechanical removal, paint remover soaking removal, heat removal, etc., and of course, the removal should be matched with the material of the first shielding layer.

Step S500, performing an anodic oxidation treatment on the component blank to form an anodic oxidation layer 50 on the surface of the component blank exposed by the second shielding layer.

Specifically, the surface of the aluminum alloy layer, that is, the appearance surface of the aluminum alloy layer, may be sequentially subjected to an appearance surface treatment by a standard anodic oxidation process, including, but not limited to, degreasing, alkaline washing, acid washing, rinsing, sand blasting, chemical polishing, anodic oxidation, dyeing, hole sealing, and other process steps.

In summary, under the design of the preparation method, before the micro-arc oxidation treatment is performed on the component rough blank, the surface of the aluminum alloy layer is shielded by the first shielding layer in advance, so that the surface of the aluminum alloy layer is prevented from being corroded by alkaline electrolyte in the micro-arc oxidation treatment process. Thus, the surface of the exposed magnesium alloy layer, the fracture of the magnesium alloy layer and the fracture of the aluminum alloy layer can be smoothly subjected to micro-arc oxidation treatment, so that the micro-arc oxidation layer 70 (with the thickness of 10-300 mu m) is protected, and excellent corrosion resistance and wear resistance are obtained.

Then, the surface of the micro-arc oxidation layer 70 is shielded by the second shielding layer to prevent the micro-arc oxidation layer 70 from being corroded by the acid electrolyte in the anodic oxidation treatment process; the first shielding layer is removed so that the surface of the aluminum alloy layer is exposed. Thus, the surface of the exposed aluminum alloy layer can be smoothly anodized, thereby protecting the anodized layer 50 (having a thickness of 5 μm to 30 μm), having an anodized appearance effect (having high glossiness, various colors and metallic texture), and obtaining excellent corrosion resistance and wear resistance.

Thus, the magnesium aluminum composite exterior member 100 of the present embodiment can be obtained.

Compared with the related art, the magnesium-aluminum composite appearance member 100 of the embodiment is based on a magnesium-aluminum composite structure, and through reasonable combination of shielding, micro-arc oxidation, anodic oxidation and other mature surface treatment processes, the lightweight advantage of the magnesium alloy is obtained, and meanwhile, the appearance texture of the anodic oxidation of the aluminum alloy and the micro-arc oxidation corrosion resistance of the magnesium alloy are maintained. Compared with the traditional aluminum alloy appearance component, the lightweight advantage is obtained; compared with the traditional magnesium alloy appearance component, the excellent appearance effect of the aluminum alloy appearance component is obtained.

As can be appreciated, in the foregoing magnesium-aluminum composite structure, the fracture of the magnesium alloy layer and the fracture of the aluminum alloy layer together with the surface layer of the magnesium alloy layer undergo micro-arc oxidation to form the micro-arc oxidation layer 70 in the magnesium-aluminum composite appearance member 100 of the embodiment; the inner layer of the magnesium alloy layer in the magnesium-aluminum composite structure is left after the micro-arc oxidation is completed to form the magnesium alloy substrate layer 30 in the magnesium-aluminum composite appearance member 100 of the present embodiment.

The surface layer of the aluminum alloy layer in the magnesium-aluminum composite structure is anodized to form the anodized layer 50 in the magnesium-aluminum composite appearance member 100 of the present embodiment; the inner layer of the aluminum alloy layer in the magnesium-aluminum composite structure is left after the end of the anodic oxidation to form the aluminum alloy base material layer 10 in the magnesium-aluminum composite appearance member 100 of the present embodiment.

In addition, in order to obtain a better anodic oxidation effect and improve the appearance of the magnesium-aluminum composite appearance member 100 in terms of appearance effect, corrosion resistance, wear resistance, and the like, the material of the aluminum alloy layer in the rough blank of the member may be one of a 1-series aluminum alloy, a 5-series aluminum alloy, a 6-series aluminum alloy, and a 7-series aluminum alloy. That is, the material of the aluminum alloy base material layer 10 of the magnesium aluminum composite exterior member 100 is one of 1-series aluminum alloy, 5-series aluminum alloy, 6-series aluminum alloy, and 7-series aluminum alloy.

As for the material of the magnesium alloy layer in the component blank, besides magnesium element, at least one of aluminum, zinc, calcium, lithium and rare earth metal element can be selected as the alloy element, and the mass fraction of the magnesium element is not less than 50%, so as to obtain the magnesium alloy with the density of 1.2g/cm ³ ～1.9g/cm ³ The magnesium alloy layer therebetween, thereby ensuring the advantage of the magnesium aluminum composite appearance member 100 in terms of light weight. That is, the magnesium alloy base material layer 30 of the magnesium-aluminum composite exterior member 100 is made of one of magnesium-aluminum alloy, magnesium-zinc alloy, magnesium-calcium alloy, magnesium-lithium alloy, and alloy of magnesium and rare earth metal element.

As for the strength properties of the member blank, the yield strength is not lower than 120MPa, and the bonding strength of the magnesium alloy layer and the aluminum alloy layer is not lower than 5N/mm ² Thereby enabling the component blank to have good resistance change when undergoing each process stepThe capability of the magnesium aluminum composite appearance member 100 is ensured, and the final shape of the magnesium aluminum composite appearance member 100 is not deviated.

Regarding the material selection of the first shielding layer, not only the corrosion resistance requirement on the alkaline electrolyte in the micro-arc oxidation treatment process needs to be met, but also the requirement of easy removal needs to be met, and for this purpose, the material of the first shielding layer can be selected from acrylic resin, epoxy resin, phenolic resin, paint with acrylic resin as a film forming substance, paint with epoxy resin as a film forming substance or paint with phenolic resin as a film forming substance.

For example, when the material of the first shielding layer is acrylic resin, the first shielding layer may be removed by heating; when the material of the first shielding layer is epoxy resin, the first shielding layer can be removed by an organic solvent soaking mode; when the material of the first shielding layer is phenolic resin, the first shielding layer can be selectively removed by laser carving, machining, chemical etching and the like; when the material of the first shielding layer is paint corresponding to the corresponding resin, the paint can be removed by brushing a paint remover.

Preferably, the thickness of the first shielding layer is 300 μm to 500 μm.

Similarly, regarding the material selection of the second shielding layer, not only the corrosion resistance requirement for the acid electrolyte in the anodic oxidation treatment process, but also the requirement for easy removal is required, for this purpose, the material of the first shielding layer may be selected from polyimide, polypropylene, polyurethane, epoxy, vinyl, phenolic, polyimide-based paint, polypropylene-based paint, polyurethane-based paint, epoxy-based paint, vinyl-based paint or phenolic-based paint.

For example, when the material of the second shielding layer is epoxy resin, the second shielding layer can be removed by soaking in an organic solvent; when the second shielding layer is made of polyimide, polypropylene, polyurethane, vinyl or phenolic resin, the second shielding layer can be selectively removed by laser etching, machining, chemical etching and the like; when the material of the second shielding layer is paint corresponding to the corresponding resin, the second shielding layer can be removed by a mode of brushing paint remover.

Of course, for the second masking layer, either removal or leaving may be selected. It will be appreciated that when the second shielding layer is selected to be left, the corrosion resistance of one side of the magnesium alloy layer is also improved, and the process of removing the second shielding layer is omitted, which is beneficial to simplifying the process and improving the efficiency.

Preferably, the thickness of the second shielding layer is 5 μm to 100 μm.

As shown in fig. 5, in an embodiment, before the step S200, that is, before the step of performing the first masking treatment on the member blank to attach the first masking layer to the aluminum alloy layer, the method further includes:

and step S600, carrying out surface roughening treatment on the aluminum alloy layer.

It can be understood that the increase of the roughening treatment process can effectively promote the surface roughness of the aluminum alloy layer, thereby greatly facilitating the attachment of the first shielding layer, improving the bonding strength of the first shielding layer and the aluminum alloy layer, further effectively guaranteeing the shielding capacity of the first shielding layer, reducing the falling risk of the first shielding layer, guaranteeing the surface of the aluminum alloy layer to be intact, enabling the subsequent treatment process to be smoothly carried out, and enabling the magnesium-aluminum composite appearance member 100 to obtain better anodic oxidation effect and micro-arc oxidation effect.

Specifically, the surface roughening treatment may be performed by at least one of a blasting process, a passivation process, an anodic oxidation process, and a micro-arc oxidation process. Preferably, the surface roughness Ra of the aluminum alloy layer subjected to the surface roughening treatment is not less than 1.5 μm.

As shown in fig. 6, in an embodiment, before the step S300, that is, "performing micro-arc oxidation treatment on the component blank to form the micro-arc oxidation layer 70 on the surface of the component blank exposed by the first shielding layer", the method further includes:

and step S700, machining the component rough blank.

It will be appreciated that, after step S200 in the first embodiment, that is, after the step of "performing the first masking treatment on the member blank to attach the first masking layer to the aluminum alloy layer", there may be a case where the first masking layer overflows at the edge of the aluminum alloy layer; at this time, by using a machining process, for example, CNC machining, the overflow portion of the first shielding layer may be removed, so as to ensure that the fracture of the magnesium alloy layer and the fracture of the aluminum alloy layer may be well exposed, and further the fracture may be fully subjected to micro-arc oxidation treatment, so as to form the micro-arc oxidation layer 70 with perfect coverage.

In addition, in order to remove the overflow portion of the first shielding layer better, a certain margin may be provided at the fracture when the rough blank of the component is processed; in this way, during the machining process, the overflow portion of the first shielding layer can be removed together with the allowance at the fracture, so that the subsequent micro-arc oxidation process can face the more fresh fracture to form the micro-arc oxidation layer 70 with more perfect coverage and more excellent performance; and the fusion of the fine shape polishing process and the removal process of the overflow part of the first shielding layer, which are performed after the rough blank of the component is processed in the traditional process, is realized, the working procedures are saved, and the efficiency is improved.

Of course, the structure such as the hole site may be machined in place during the machining process.
