Problems solved by technology

However, the vacuum coating technology also has certain limitations. In the process of preparing a pure black film layer, it is easy to appear different colors, blue in black or red in black, etc., which seriously affects the appearance of the black film.
It has been reported that the best L* (lightness value) of the black film layer can only reach about 35. It is difficult to continue to reduce the L* of the film layer in order to obtain a purer black color.

Embodiment Construction

[0016] see figure 1 , the coating member 10 of the preferred embodiment of the present invention includes a base 11 and a color layer 13 formed on the base 11 .

[0017] The material of the base body 11 can be one of metal, glass, ceramic and plastic.

[0018] The color layer 13 is a boron-carbon-nitrogen layer with a thickness of 300-700nm. The color layer 13 visually presents black to the naked eye, and the chromaticity region presented by the CIE LAB color system has L* coordinates between 32 and 35, a* coordinates between 0.6 and 1, and b* coordinates between 0.8 to 1. The color layer 13 is formed by magnetron sputtering.

[0019] The coating part 10 can be a casing of electronic devices such as notebook computers and personal digital assistants, or a decorative component of other products.

[0020] The manufacturing method of above-mentioned coating member 10, comprises the following steps:

[0021] A substrate 11 is provided. The material of the substrate 11 can be...

Abstract

The invention provides a coated member, which comprises a matrix and a color layer formed on the matrix. The color layer is a boron-carbon-nitrogen layer. L* coordinate of chroma area presented by the color layer in a CIELAB color system is between 32 and 35; a* coordinate is between 0.6 and 1; and b* coordinate is between 0.8 and 1. The invention also provides a manufacturing method of the above coated member. The color layer of the coated member can make the coated member show black. Therefore, the color of a vacuum coating layer is enriched.

Description

technical field [0001] The invention relates to a coating part and a manufacturing method thereof, in particular to a coating part with a black appearance and a manufacturing method thereof. Background technique [0002] The application of black coating is mainly to eliminate or reduce the influence of light, or as a decorative coating on the surface of the product. At present, the most commonly used method for preparing black coating is electrochemical method, such as anodic oxidation black film, electroplating black nickel or black chrome, etc., but this kind of method pollutes heavily and is not environmentally friendly. [0003] Vacuum coating technology is a very environmentally friendly film forming technology. 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, so the application of vacuum coating in the field of decorative surface ...
