Problems solved by technology

However, plastic shells and painted shells cannot present a good metallic texture
Although the film layer formed by vacuum coating has the advantages of high hardness, high wear resistance, good chemical stability, firm combination with the substrate, and bright metal appearance, the vacuum coating technology itself is relatively complicated and difficult to precisely control. , and 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, anodic treatment and other processes, the color of the vacuum coating layer is not rich enough, which limits its competitiveness in the field of decorative coating

Embodiment 1

[0031] (1) pre-coating treatment

[0032] The substrate 11 was ultrasonically cleaned with acetone for about 5 minutes.

[0033] Put the cleaned substrate 11 into the turntable in the coating chamber of the magnetron sputtering coating machine. The surface of the substrate 11 is cleaned with argon plasma. Vacuumize the coating chamber to a vacuum degree of 3×10 -5 Torr, the flow rate of argon gas is 500sscm, the bias voltage applied to the substrate is -150V, and the plasma cleaning time is 10min. The magnetron sputtering coating machine used in this embodiment is produced by Nanfang Innovation Company, and the model is SM-1100H-D.

[0034] (2) Magnetron sputtering forms bonding layer 13

[0035] After the plasma cleaning is completed, use argon as the working gas, adjust its flow rate to 280 sccm, heat the coating chamber to 100°C, turn on the power supply of the aluminum target that has been placed in the magnetron sputtering coating machine, and set its power 8kw, a bi...

Abstract

The invention relates to a vacuum coating piece. The vacuum coating piece comprises a basal body, a bonding layer and a color layer, wherein the bonding layer is formed on the surface of the basal body; the color layer is formed on the surface of the bonding layer and is an A1-N film; a chromaticity region presented by the color layer in a CIE LAB color system has an L* coordinate value of 48 to 83, an a* coordinate value of -12 to -5 and a b* coordinate value of -45 to -17. The invention also provides a manufacturing method of the vacuum coating piece. The vacuum coating piece presents a blue appearance which enriches the color of a vacuum coating layer.

Description

technical field [0001] The invention relates to a vacuum coating part and a manufacturing method thereof, in particular to a vacuum coating part with blue and metallic 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 can be 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. Although the film layer formed by vacuum coating has the advantages of high hardness, high wear resistance, good chemical stability, firm combination w...
