A shell. The shell contains a matrix, an anchor coat and a color layer. The anchor coat is formed on the surface of the matrix. The color layer is formed on the surface of the anchor coat. The color layer is a Ti-O-N film. L* coordinate figure of the chromatic region presented by the color layer in the CIE LAB color system is between 52 to 57; a* coordinate figure is between -15 to -25; and b*coordinate figure is between -10 to -18. The invention also provides a manufacturing method of the above shell. The shell presents a dark blue appearance, and the color of a vacuum coating layer is abundant.
Description
Technical field
The present invention relates to a kind of housing and preparation method thereof, relate in particular to a kind of housing and preparation method thereof with mazarine and metal-like.
Background technology
Along with the continuous progress of science and technology, mobile phone, personal digital assistant (PDA, Personal Digital Assistant), and various electronic installation such as computingmachine also develop rapidly, its function is also more and more abundant.For the shell that makes electronic installation has rich colors, colored plastic capable of using traditionally forms the colored plastic shell, or forms the colorant layer by the mode of spraying paint at the surface of shell of electronic installation.Yet plastic casing can not present good metal texture with the shell that sprays paint.On the other hand; Being difficult for precision owing to vacuum coating technology itself is comparatively complicated controls; The color of the metal vacuum coatings that forms in surface of shell in the prior art is limited; Compare with technologies such as baking vanish, anodizing, the color of vacuum coating is abundant inadequately, has seriously limited its power such as compete in the decoration film coating field.
Summary of the invention
In view of this, the present invention provides a kind of housing with mazarine and metal-like.
In addition, the present invention also provides a kind of making method of above-mentioned housing.
A kind of housing; This housing comprises matrix, key coat and color layer, and said key coat is formed at the surface of matrix, and said color layer is formed at the surface of key coat; Said color layer is the Ti-O-N film, and the chroma areas that this color layer appears is in the L of CIE LAB colour system
*Coordinate figure between 52 to 57, a
*Coordinate figure between-15 to-25, b
*Coordinate figure is between-10 to-18.
A kind of making method of housing, it comprises the steps:
Matrix is provided, at surface magnetic control sputtering one key coat of this matrix, at surface magnetic control sputtering one color layer of this key coat; The said color layer of magnetron sputtering is target with the titanium; With oxygen and nitrogen is reactant gases, and the flow of oxygen is 5-15sccm, and the flow of nitrogen is 45～55sccm; Said color layer is the Ti-O-N film, and the chroma areas that said color layer appears is in the L of CIE LAB colour system
*Coordinate figure between 52 to 57, a
*Coordinate figure between-15 to-25, b
*Coordinate figure is between-10 to-18.
The preparation method of said housing; When forming color layer; Adopt the titanium target as target; Through control, thereby realize the microcosmic bonding structure between each proportional relationship of all ingredients and each composition in the required color layers, make color layer demonstrate navy blue purpose thereby reach to the flow of reactant gases nitrogen and oxygen.Can demonstrate attractive navy blue metal appearance with the prepared housing of this method, enrich the color of vacuum coating, greatly improve the outward appearance competitive power of product.
