In view of this, the present invention provides a kind of housing with red-purple and metal-like.
In addition, the present invention also provides a kind of making method of above-mentioned housing.
A kind of 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, and said color layer is the Zr-N film, and the chroma areas that this color layer appears is in the L of CIE LAB colour system
*Coordinate figure between 25 to 30, a
*Coordinate figure between 40 to 45, b
*Coordinate figure is between-45 to-40.
A kind of making method of housing, it comprises the steps:
Matrix is provided;
Surface magnetic control sputtering key coat at this matrix;
Surface magnetic control sputtering color layer at this key coat; The processing parameter of the said color layer of magnetron sputtering is: with the zirconium is target, is reactant gases with nitrogen, and argon gas is a working gas; The total flow of nitrogen and argon gas is 150～700sccm, and the branch of nitrogen covers 35～50% of total gas pressure intensity; Said color layer is the Zr-N film, and the chroma areas that said color layer appears is in the L of CIE LAB colour system
*Coordinate figure between 25 to 30, a
*Coordinate figure between 40 to 45, b
*Coordinate figure is between-45 to-40.
The preparation method of said housing; When forming color layer; Adopt the zirconium target as target; Through to reactant gases nitrogen and the control of working gas argon gas total flux and the control of nitrogen partial pressure, thereby realize the microcosmic bonding structure between each proportional relationship of all ingredients and each composition in the required color layer, make color layer demonstrate mauve purpose thereby reach.Can demonstrate attractive mauve metal appearance with the prepared housing of this method, enrich the color of vacuum coating, improve the outward appearance competitive power of product widely.
