Abstract
This invention relates to a shell of a portable electronic device including Mg alloy backing and an AlTiN layer, in which, the AlTiN layer covers the surface of the Mg alloy backing. A method for manufacturing the shell includes the following steps: providing a Mg alloy backing, putting it in a vacuum filming chamber with Al and Ti as the sputter target, pumping the chamber and inletting a mixed gas with small amount of N2 and inert gas and sputtering the heated Mg alloy to get the shell of a portable electronic device.
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 nitride titanium layer, wherein this aluminium nitride titanium layer is covered in the outside of magnesium alloy base material and forms the use face of this portable case of electronic equipment.
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 this vacuum coating is indoor to be sputtering target material with aluminum metal and titanium;
To the indoor vacuum degree that is evacuated to of this vacuum coating is 0.1-1.0 Pascal;
To the gaseous mixture of indoor feeding small amount of nitrogen of vacuum coating and inert gas, and make the indoor vacuum degree of vacuum coating between 5-50 Pascal;
Behind the heating magnesium alloy, it is carried out the shell that sputter obtains portable electron device, the temperature of this sputter is between 200-350 ℃.
Compare prior art, portable case of electronic equipment of the present invention has an aluminium nitride titanium layer, this TiAlN rete has very strong hardness and resistance to wear, it is smooth that portable electron device is kept clean, the present invention simultaneously also by the ratio of aluminium and titanium in the adjustment TiAlN, can make portable case of electronic equipment have the outward appearance of different colours.
[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 nitride titanium layer 20, and wherein this aluminium nitride titanium layer 20 is covered in the outside of this magnesium alloy base material 10 and forms the use face of this portable case of electronic equipment 1.When wherein the aluminium atomic mass percentage composition in the aluminium nitride titanium layer 20 is 1-5%, the aluminium nitride titanium layer presents golden yellow, aluminium atomic mass percentage composition was greater than 5% to 40% o'clock, the aluminium nitride titanium layer presents silvery white, when aluminium atomic mass percentage composition greater than 50% the time, the aluminium nitride titanium layer presents pansy, and along with aluminium atomic mass percentage composition is high more, purple is obvious more.
The manufacture method of this portable case of electronic equipment 1 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 this vacuum coating is indoor to be sputtering target material with aluminum metal and titanium;
Vacuumize this vacuum coating is indoor;
Gaseous mixture to indoor feeding small amount of nitrogen of vacuum coating and inert gas;
Behind the heating magnesium alloy, it is carried out the shell that sputter obtains portable electron device.
Wherein before the sputter, the indoor vacuum degree of vacuum coating need be evacuated to 0.1-1.0 Pascal.The inert gas that mixes with nitrogen can be Ar, Kr or Xe.The vacuum degree that feeds in the gaseous mixture final vacuum coating chamber is 5-50 Pascal.Temperature should remain 200-350 ℃ during the magnesium alloy sputter.
