Problems solved by technology

However, plastic shells and painted shells cannot present a good metallic texture
On the other hand, due to the complex technology of vacuum coating itself, it is not easy 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. Abundant, which severely limits its competitiveness in the field of decorative coatings

Embodiment Construction

[0016] 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 .

[0017] The substrate 11 is made of stainless steel or glass.

[0018] The bonding layer 13 is formed on the surface of the substrate 11 by magnetron sputtering. The bonding layer 13 is a titanium metal film with a thickness of 0.1-0.2 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.

[0019] The color layer 15 is a Ti-N-C film formed by magnetron sputtering. The thickness of the color layer 15 is between 0.2-0.3 μm. The color layer 15 exhibits a bronze color, and the chromaticity region exhibited in the CIE LAB c...

Abstract

The invention relates to a shell and a manufacturing method thereof. The shell comprises a substrate, a bonding layer and a color layer, wherein the surface of the substrate is provided with the bonding layer, and the color layer is covered on the bonding layer of the substrate. The bonding layer is a titanium metal layer, and the color layer is a Ti-N-C membrane, wherein a chromaticity area presented on the color layer is between 45.39 and 47.50 at the L* coordinate of a CIE LAB color system, between 13.07 and 12.42 at the a* coordinate of the CIE LAB color system, and between 13.26 and 18.56 at the b* coordinate of the CIE LAB color system. The invention also provides a magnetron sputtering manufacturing method of the shell. The shell and the manufacturing method can achieve the effect that the color layer presents a bronze color, so the color of a vacuum plating layer is enriched.

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof, in particular to a casing with bronze color and metal texture 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 technology of vacuum coating itself is relatively complicated and difficult to be precisely controlled, the color of the metal vacuum coating lay...
