Abstract

The invention provides a housing and a manufacturing method thereof. The housing comprises a substrate and a color layer formed on a surface of the substrate, wherein the color layer comprises a nitrogen oxygen titanium layer and an aluminium oxide layer which are formed in sequence on the surface of the substrate, and a chrominance area of the color layer lies in a CIE LAB color system with an L * coordinate between 49 and 53, an a * coordinate between -10 and -9 and a b * coordinate between -39 and -37. The invention also provides a manufacturing method of the above-mentioned housing. The color layer can enable the housing to present a color of purplish blue, so that colors of vacuum coating layers are enriched.

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof, in particular to a casing with a dark 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 less. Contents of the ...
