Abstract
A shell of portable electronic device consists of mg alloy base material and AI alloy film coating layer. Its preparing method includes placing mg alloy base material in vacuum film coating chamber and vacuuming said chamber, using AI metal as sputter - coating target material to sputter - coat a layer of AI alloy coating film on mg alloy base material surface, carrying out anode treatment on AI alloy to form a anode treated layer on AI alloy surface.
Description
[technical field]
The invention relates to a kind of portable case of electronic equipment and manufacture method thereof.
[background technology]
Portable electron device all has a shell that prevents electromagnetic radiation as digital camera, PDA(Personal Digital Assistant), mobile phone etc.Existing portable case of electronic equipment is plastic casing applying metal thin layer (as an aluminium), as United States Patent (USP) the 6th, 207, No. 089, for reducing portable electron device electromagnetic interference on every side, eliminate accumulation of static electricity, it is bonded to the superplastic alloy thin slice on the inner surface of plastic casing by adhesive.But when being to use this method,, make alloy sheet easily come off or wrinkling because of alloy sheet and plastic casing adhesion are not strong.Industry is also adopted the shell (as aluminium alloy, magnesium alloy etc.) of alloying metal as portable electron device in addition, comparatively speaking, magnesium alloy case has better rigidity, thermal diffusivity, corrosion-resistant and anti-electromagnetic-radiation ability than plastic casing, simultaneously with respect to aluminum alloy casing, magnesium alloy case has lower density, better anti-seismic performance, can satisfy portable electron device and pursue frivolous needs.
Yet because the hardness and the anti-wear performance of magnesium alloy case is relatively poor, cause the magnesium alloy case surface shortcoming of wearing and tearing easily,, thereby cause dull coloring to lose attraction easily client simultaneously because magnesium alloy only has independent silvery appearance.
In view of this, provide a kind of have good abrasion resistance and have the portable case of electronic equipment of various appearances color and manufacture method real in necessary.
[summary of the invention]
The object of the present invention is to provide a kind of portable case of electronic equipment that has good abrasion resistance and have the various appearances color.
Another object of the present invention is to provide a kind of manufacture method of above-mentioned portable case of electronic equipment.
In order to realize purpose of the present invention, the invention provides a kind of portable case of electronic equipment, comprise magnesium alloy base material and aluminium alloy coatings, wherein this aluminium alloy coatings is covered in the magnesium alloy substrate surface, and this aluminium alloy coatings surface is formed with an anodization through anode treatment.
A kind of manufacture method of portable case of electronic equipment may further comprise the steps:
One magnesium alloy base material is provided, and the polishing back is cleaned;
It is indoor that this magnesium alloy base material is put into vacuum coating, and vacuumize this vacuum coating is indoor;
With the aluminum metal sputtered target material, at magnesium alloy substrate surface sputter layer of aluminum alloy coating layer;
This aluminium alloy is carried out anode treatment, form one deck anodization on its surface.
Compare prior art, the aluminium alloy coatings surface of portable case of electronic equipment of the present invention is formed with one deck anodization, this anodization has very strong hardness and resistance to wear, the character that can improve Mg alloy surface also keeps the characteristic of magnesium alloy materials light weight simultaneously, and has the color outward appearance of all styles of by anode treatment in the anodization that aluminium alloy coatings surface generates.
[description of drawings]
Fig. 1 is the structural representation of portable case of electronic equipment of the present invention.
[embodiment]
Portable case of electronic equipment of the present invention is applicable to portable electron devices such as mobile phone, PDA, digital camera.
With reference to shown in Figure 1, portable case of electronic equipment 1 of the present invention comprises magnesium alloy base material 10 and aluminium alloy coatings 20, wherein this aluminium alloy coatings 20 is covered in magnesium alloy base material 10 surfaces, and these aluminium alloy coatings 20 surfaces are formed with an anodization 30 through anode treatment.
The manufacture method of this portable case of electronic equipment 1 may further comprise the steps:
One magnesium alloy base material 10 is provided, and the polishing back is cleaned;
It is indoor that this magnesium alloy base material 10 is put into vacuum coating, and vacuumize this vacuum coating is indoor;
With the aluminum metal is sputtered target material, in magnesium alloy base material 10 surperficial sputter layer of aluminum alloy coating layers 20;
This aluminium alloy is carried out anode treatment, form one deck anodization 30 in its surface.
Wherein need before the anode treatment aluminium alloy coatings 20 is carried out oil removing and corrosion treatment, can utilize trichloroethylene to carry out oil removing, in sodium hydrate aqueous solution, carry out corrosion treatment.Then utilize sulfuric acid, phosphoric acid, chromic acid or oxalic acid electrolyte that aluminium alloy coatings 20 is carried out anodized, form an anode oxide film (figure does not show), adopt dye-impregnated colouring or electrocolor process that this anode oxide film is carried out painted processing back and form a colored anodization 30, thereby obtain having the portable case of electronic equipment 1 of coloured appearance.Wherein when using sulfuric acid liquid as anode treatment liquid, this anodization 30 is a colourless transparent film, and when using chromic acid as anode treatment liquid, this anodization 30 is grey or celadon, when using oxalic acid as anode treatment liquid, this anodization 30 is yellow.After the painted processing, need that the colored anodization 30 on surface is carried out sealing of hole and handle, can adopt hot water method of pore sealing, steam method of pore sealing, nickel salt method of pore sealing etc.Because the anodization 30 through anode treatment has stronger corrosion resistance and resistance to wear, so portable case of electronic equipment of the present invention 1 has stronger corrosion resistance and resistance to wear simultaneously.
