Embodiment

See also Fig. 1, the housing 10 of the present invention's one preferred embodiment is that example is explained with a handset shell.This housing 10 comprises matrix 11, binder course 13 and color layer 15.This binder course 13 is arranged at the surface of matrix 11, and this color layer 15 is arranged at the surface of binder course 13.

Matrix 11 is to be nonmetallic materials such as metal material or glass, plastics.

In conjunction with consulting Fig. 2, a coating machine 100 is provided, this coating machine 100 comprises a coating chamber 20 and is connected in a vacuum pump 30 of coating chamber 20 that vacuum pump 30 is in order to vacuumize coating chamber 20.Be provided with pivoted frame (not shown), the symmetrically arranged titanium target 22 in center in this coating chamber 20, pivoted frame drives matrix 11 along 21 revolution of circular track, and matrix 11 also rotation along track 21 revolution the time.Binder course 13 is formed at the surface of matrix 11 with the mode of magnetron sputtering.This binder course 13 is a titanium metal film, and its thickness is between 0.1～0.2 μ m.

The color of this binder course 13 is for not influencing the thin shade of color layer 15 colors, such as can be thin shades such as silver color, white and canescence.

Color layer 15 is the Ti-O-N film, and its mode with magnetron sputtering forms.The thickness of this color layer 15 is between 0.3～0.5 μ m.This color layer 15 demonstrates green, and between 72 to 80, the a* coordinate figure is between-12 to-6 in the L* coordinate figure of CIE LAB colour system for its chroma areas that appears, and the b* coordinate figure is between 22 to 28.

Please consult Fig. 1 and Fig. 2 in the lump, the manufacture method of housing 10 of the present invention may further comprise the steps:
