Summary of the invention
In view of this, the present invention provides a kind of housing that presents garnet and metal-like.
In addition, the present invention also provides a kind of manufacture method of above-mentioned housing.
A kind of housing; It comprises a matrix, a binder course and a color layer, and said binder course is formed at the surface of matrix; Said color layer is formed at the surface of binder course; Between 52 to 54, the a* coordinate is between 10 to 13 in the L* of CIELAB colour system coordinate for the chroma areas that said color layer appears, and the b* coordinate is between 5.5 to 5.6.
A kind of method for producing shell, it comprises the steps:
One matrix is provided, forms a binder course at the surface by utilizing magnetron sputtering of this matrix, said binder course is a titanium metal film, and its thickness is 0.1~0.2 μ m.Surface by utilizing magnetron sputtering at this binder course forms a color layer, and said color layer is target with the titanium, and the flow of control nitrogen is between 110 to 150sccm; The total flow of acetylene is between 5 to 20sccm; Said color layer is a Ti-N-C film, and its thickness is 0.2~0.3 μ m, the chroma areas that appears in the L* coordinate of CIE LAB colour system between 52 to 54; The a* coordinate is between 10 to 13, and the b* coordinate is between 5.5 to 5.6.
Compared to prior art, the preparation method of said housing when forming color layer, through to the design of reacting gas acetylene and nitrogen flow with to the control of thicknesses of layers, makes color layer demonstrate puniceous purpose thereby reach.Can demonstrate the metal appearance of attractive garnet with the prepared housing of this method, enrich the color of vacuum coating, greatly improve the outward appearance competitiveness of product.
