Embodiment
The making method of the housing 10 (as shown in Figure 1) of preferred embodiments of the present invention comprises the steps:
Transparent matrix 11 is provided, and this matrix 11 can be transparent glass or transparent plastics.This matrix 11 comprises internal surface 112 and outside surface 114.
Matrix 11 is carried out surface cleaning,, clean the dry for standby afterwards that finishes with the impurity of removing matrix 11 surface and greasy dirt etc.Said cleaning comprises that matrix 11 is put into the ultrasonic cleaner that is loaded with ethanol and/or acetone soln shakes cleaning.
Outside surface 114 to matrix 11 covers, in case outer surface 114 pollutes when terminating in internal surface 112 and forming composite films 13.Use high temperature gummed tape outer surface 114 to cover at this preferred embodiment.
Matrix 11 is fixed on the magnetron sputtering coater pivoted frame of (figure does not show), vacuumizes cavity to 8 * 10 of this coating equipment
-3Pa; And the temperature that makes this cavity remains on about 0 ℃, and the feeding flow is the high-purity argon gas (working gas) of 400～450sccm (standard state ml/min), is reactant gases with oxygen and nitrogen; Oxygen flow is 12～18sccm, and nitrogen flow is 115～120sccm; Open the power supply of titanium target; Setting power is 8～12kw, and the revolution rotating speed that pivoted frame is set be 3 rpms (revolution per minute, rpm); Internal surface 112 to matrix 11 carries out magnetron sputtering, on this internal surface 112, to form titanyl nitrogen rete 131.The time that sputter forms this titanyl nitrogen rete 131 is 50～70 minutes.
Behind the said titanyl nitrogen of the sputter rete 131, close the titanium target, stop to feed nitrogen and oxygen, opening the chromium target then and regulating the chromium target power output is 8～10kw, proceeds magnetron sputtering, on this titanyl nitrogen rete 131, to form chromium rete 133.The time that sputter forms this chromium rete 133 is 0.5 hour.
After said chromium rete 133 forms, promptly make said composite film 13.
Magnetron sputtering tears high temperature gummed tape after accomplishing.
The outside surface 114 that the composite film of making according to above-mentioned steps 13 sees through matrix 11 is yellow, and has preferable metal-like.(L*, a* b*) are (82～85 ,-3～2,20～23) to the tristimulus coordinates that described composite film 13 appears in titanyl nitrogen rete 131 1 sides.
Because composite film 13 is formed at the internal surface 112 of matrix 11, during use, can be with outside surface 114 as appearance, thereby can avoid composite film 13 scratches or come off.
The making method of said housing 10 is passed through in the internal surface 112 magnetron sputtering titanyl nitrogen retes 131 of transparent matrix 11 and the composite film 13 of chromium rete 133; And through flow rate of reactive gas, sputtering time etc. in the control sputter procedure; So that said composite film 13 forms specific microtexture, and make said housing 10 demonstrate yellow and the outward appearance of metal-like is arranged.
Please consult Fig. 1 again, comprise transparent matrix 11 and be formed at the composite film 13 on the matrix 11 by the prepared housing 10 of aforesaid method.
Matrix 11 can be transparent glass or plastics.Matrix 11 comprises that internal surface 112 reaches and these internal surface 112 opposed outer surface 114, and this outside surface 114 is the appearance of this housing, and this composite film 13 is formed on this internal surface 112.
Composite film 13 comprises titanyl nitrogen rete 131 and chromium rete 133.This titanyl nitrogen rete 131 directly is formed at the internal surface 112 of matrix 11.Chromium rete 133 is formed on this titanyl nitrogen rete 131; The transmittance of said chromium rete 133 is lower, and it can stop light to see through well, plays the effect of substrate for titanyl nitrogen rete 131; Make chroma areas that this composite film 13 appeared in titanyl nitrogen rete 131 1 sides in the L* coordinate figure of CIE LAB colour system between 82 to 85; The a* coordinate figure is between-3 to 2, and the b* coordinate figure is rendered as yellow between 20 to 23.
Be noted that above-mentioned embodiment is merely preferred embodiments of the present invention, those skilled in the art also can do other variation in spirit of the present invention.These all should be included within the present invention's scope required for protection according to the variation that the present invention's spirit is done.
