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. At present, the PVD film layer that can be widely prepared and used is mainly golden yellow, black, white and other colors, and the color that can be stably produced even less

Embodiment Construction

[0027] see figure 1 The housing 10 of the preferred embodiment of the present invention includes a base 11 , a base layer 12 formed on the base 11 , a transition layer 13 formed on the base layer 12 and a color layer 14 formed on the transition layer 13 . The color layer 14 is yellowish-brown visually.

[0028] The material of the substrate 11 can be one of stainless steel, glass, ceramics and plastic.

[0029] The primer layer 12 is an aluminum metal layer with a thickness of about 0.1-0.2 microns. The primer layer 11 is used to improve the bonding force of subsequent coatings.

[0030] The transition layer 13 consists of aluminum oxynitride (AlON). The mass percent content of aluminum element in the transition layer 13 is 60%-65%, the mass percent content of oxygen element is 30%-35%, and the mass percent content of nitrogen element is 5%-10%. The thickness of the transition layer 13 is about 0.2-0.6 microns. The transition layer 13 is used to better improve the binding ...

Abstract

The invention provides a shell with a yellowish-brown appearance, comprising a color layer. The color layer is made of an aluminum oxynitride compound; the color layer comprises the following element in mass percent of 45-50% of aluminum, 40-45% of oxygen, and 10-15% of nitrogen; and an L* coordinate of a chroma area shown by the color layer ranges from 28 to 35 in a LAB color specification system of the CIE (International Commission on Illumination), an a* coordinate of the chroma area shown by the color layer ranges from 4 to 6, and a b* coordinate of the chroma area shown by the color layer ranges from 9 to 11. The invention further provides a manufacturing method of the shell. The color layer of the shell enables the shell to be yellowish-brown which is difficult to show in vacuum plating, so as to enrich the color of the vacuum plating.

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof, in particular to a casing with a yellow-brown appearance and a manufacturing method thereof. Background technique [0002] In order to make the casing of the electronic device rich in color, decorative coatings are currently prepared mainly through processes such as anodic oxidation, baking varnish, and porcelain baking. Compared with these traditional processes, PVD coating technology is more green and environmentally friendly, and the use of PVD coating technology can form a decorative color layer with a metallic texture on the surface of the product shell. [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. At present, the PVD film layer that can be widely prepared and used is mainly golden yellow, black, white and other colors, and the color that can be stably produced Even less. Contents...
