Problems solved by technology

In order to make the casing of the electronic device present a bright blue color with a metallic texture, in the prior art a thin optical film is formed on the casing through an optical coating process, and the optical film obtains a bright blue color through the interference principle of light. However, Because the optical film is very thin and not wear-resistant; moreover, usually the optical film will show different colors from different angles, so the bright blue color presented by the optical film is unstable

Embodiment 1

[0042] 1. Ultrasonic cleaning

[0043] The substrate 11 made of stainless steel (model 316L) was put into an ethanol solution for ultrasonic cleaning to remove impurities and oil stains on the surface of the substrate 11, and dried for later use after cleaning.

[0044] 2. Coating

[0045] Magnetron sputtering equipment (produced by Shenzhen Nanfang Innovation Vacuum Technology Co., Ltd., model SM-1100H. The magnetron sputtering equipment includes a vacuum chamber, a turntable, a magnetron target and a bias power supply. The magnetron target is a target structure , including two pairs of chromium targets, a certain distance is formed between each pair of targets. The substrate is fixed on the turntable, and the turntable drives the substrate to pass between each pair of chromium targets when the turntable rotates.

[0046] Target washing: adjust the absolute pressure in the vacuum chamber to 6.0×10 -3 Pa, then pass argon gas into the vacuum chamber until the pressure is 0.8 ...

Abstract

The invention provides a housing with a blue appearance. The housing comprises a matrix, a bonding layer which is arranged on the surface of the matrix and a hardened layer which is arranged on the bonding layer and a color layer which is arranged on the hardened layer. The hardened layer is composed of a chromium element and a carbon element. The color layer is composed of the chromium element, an oxygen element and a nitrogen element. An atom number ratio of the chromium element, the oxygen element and the nitrogen element in the color layer is (0.8-1.0):(1.2-1.5):(0.3-0.5). The L* coordinate figure of a chromatic area displayed by the color layer in the CIE (commission international eclairage) LAB surface color system ranges from 35 to 40, the a* coordinate figure ranges from 0 to 3, and the b* coordinate figure ranges from -10 to -15. The color layer is in a stable and bright-colored blue color, so the housing can show the blue appearance with metal texture. The invention further provides a manufacturing method of the housing.

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof, in particular to a casing with a bright blue metal appearance and a manufacturing method thereof. Background technique [0002] Vibrant blue is an attractive color. In order to make the casing of the electronic device present a bright blue color with a metallic texture, in the prior art a thin optical film is formed on the casing through an optical coating process, and the optical film obtains a bright blue color through the interference principle of light. However, Because the optical film is very thin and not wear-resistant; moreover, usually the optical film will show different colors when viewed from different angles, so the bright blue color presented by the optical film is unstable. Contents of the invention [0003] In view of this, the present invention provides a metallic bright blue appearance and wear-resistant housing. [0004] In addition, the present invention also ...
