Problems solved by technology

[0003] However, in the prior art, the color of the film layer formed on the surface of the shell by PVD coating technology is very limited, and the PVD film layer that can be widely prepared and used at present is mainly golden yellow, black and other colors.
Compared with baking paint, anodic treatment and other processes, the color of the vacuum coating layer is not rich enough, which seriously limits its competitiveness in the field of decorative coating

Embodiment Construction

[0016] see figure 1 , The casing 10 of a preferred embodiment of the present invention includes a base 11 and a color layer 13 formed on the surface of the base 11 . The color layer 13 appears purple.

[0017] The substrate 11 can be metal, glass or ceramic.

[0018] The color layer 13 can be formed on the surface of the substrate 11 by magnetron sputtering. The color layer 13 is aluminum fluoride-aluminum oxide (AlF 3 -Al 2 o 3 ) layer, the thickness of which may be 0.1-0.6 μm. This color layer 13 presents purple, and the chromaticity area that it presents is in the L of CIE LAB color system. * Coordinates between 35 and 55, a * Coordinates between 5 and 15, b * Coordinates are between 25 and 28.

[0019] The manufacturing method of the casing 10 of the present invention comprises the following steps:

[0020] A substrate 11 is provided. The substrate 11 can be metal, glass or ceramic.

[0021] The substrate 11 is pretreated, and the pretreatment may include steps...

Abstract

The invention provides a shell provided with a purple surface, and the shell comprises a base body and a color layer formed on the surface of the base body, wherein the color layer is a layer made from aluminum fluoride and aluminum oxide, an L*coordinate of a chroma area presented by the color layer to a CIE LAB color system is arranged between 35 and 55, an a*coordinate is arranged between 5 and 15, and a b*coordinate is arranged between 25 and 28. The invention also provides a manufacturing method for the shell. The shell can be presented to be a purple effect by the color layer, therefore, colors of a vacuum coating layer can be abundant.

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof, in particular to a casing with a purple appearance and a manufacturing method thereof. Background technique [0002] In order to make the casing of the electronic device rich in color, traditionally, colored plastics can be used to form the colored plastic casing, or a color layer can be formed on the surface of the casing of the electronic device by spraying paint. However, plastic shells and painted shells cannot present a good metallic texture. The use of PVD coating technology can form a metallic color layer on the surface of the shell. [0003] However, in the prior art, the color of the film layer formed on the surface of the casing by PVD coating technology is very limited, and the PVD film layer that can be widely prepared and used at present is mainly golden yellow, black and other color systems. Compared with baking paint, anodic treatment and other processes, the color o...
