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 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 light blue.

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

[0029] The color layer 13 can be formed on the surface of the substrate 11 by magnetron sputtering. The color layer 13 includes a titanium oxynitride layer 131 and a chromium oxynitride layer 133 sequentially formed on the surface of the substrate, and the thickness of the color layer 13 is 0.3-1.0 μm. The color layer 13 visually presents light blue to the naked eye, and the chromaticity region it presents is in the L range of the CIE LAB color system. * Coordinates between 60 and 100, a * Coordinates between -10 and -8, b * Coordinates are between -15 and -13.

[0030] The mass percentages of Ti, O and N in the titanium oxynitride layer are 40% to...

Abstract

The invention provides a housing with a light blue appearance. The housing comprises a matrix and a color layer formed on the surface of the matrix, wherein the color layer comprises a nitrogen titanium oxide layer and a nitrogen chromium oxide layer which are formed on the surface of the matrix in sequence; and a chroma region presented by the color layer has an L* coordinate between 60 to 100, an a* coordinate between minus 10 to minus 8 and a b* coordinate between minus 15 to minus 13 in a CIE LAB surface color system. The invention further provides a manufacturing method of the housing. By adopting the color layer, the housing can present a light blue color, thereby enriching the color of a vacuum coating layer.

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof, in particular to a casing with a light blue 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 o...
