Problems solved by technology

However, plastic shells and painted shells cannot present a good metallic texture
On the other hand, because the vacuum coating technology itself is relatively complicated and difficult to precisely control, the color of the metal vacuum coating layer formed on the surface of the shell in the prior art is limited. Compared with baking paint, anodizing and other processes, the color of the vacuum coating layer is not enough. rich, limiting its competitiveness in the field of decorative coatings

Embodiment Construction

[0015] see figure 1 , the casing 10 of a preferred embodiment of the present invention can be a casing of a mobile phone. The casing 10 includes a base 11 , a bonding layer 13 and a color layer 15 . The combination layer 13 is disposed on the surface of the substrate 11 , and the color layer 15 is disposed on the surface of the combination layer 13 .

[0016] The substrate 11 can be metal material or non-metallic material such as glass and plastic.

[0017] The bonding layer 13 is formed on the surface of the substrate 11 by DC magnetron sputtering. The bonding layer 13 is a titanium metal film with a thickness of 0.1-0.3 μm. The color of the bonding layer 13 is a light tone that does not affect the color of the color layer, such as silver, white, off-white and other light tones.

[0018] The color layer 15 is a Zr-N film, which is formed by DC magnetron sputtering. The thickness of the color layer 15 is between 0.3-0.5 μm. This color layer 15 presents golden yellow, and...

Abstract

The invention relates to a shell. The shell comprises a substrate, a bonding layer and a color layer, wherein the bonding layer is formed on the surface of the substrate, the color layer is formed on the surface of the binding layer, the color layer is a Zr-N membrane, the L<*> coordinate value of the chromaticity area presented by the color layer on the CIE LAB surface color system is 55-65, the a<*> coordinate value is 10-20, and the b<*> coordinate value is 30-40. The present invention further provides a manufacture method for the shell. The shell presents a golden yellow appearance so as to enrich the color of the vacuum coating layer.

Description

technical field [0001] The invention relates to a housing and a manufacturing method thereof, in particular to a golden yellow and metallic housing and a manufacturing method thereof. Background technique [0002] With the continuous advancement of technology, various electronic devices such as mobile phones, personal digital assistants (PDA, Personal Digital Assistant), and computers are also developing rapidly, and their functions are becoming more and more abundant. 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 is 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. On the other hand, because the vacuum coating technology itself is relatively complicated and difficult to precisely control, the color of the metal vacuum coating layer formed on the...
