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 C x N layers, where 2 / 3≦x≦3. The color layer 13 visually presents black to the naked eye, and its chromaticity area in 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 and 1. between. The color layer 13 has a thickness of 500-700 μm. 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 s...

Abstract

The invention provides a coated member, which comprises a matrix and a color layer formed on the matrix. The color layer is a CxN layer, wherein x is less than or equal to 3 and greater than or equal to 2/3. 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] PVD coating technology is a more environmentally friendly coating process. In the prior art, titanium carbide (TiC) and chromium carbide (CrC) are the most widely used industrial coatings for the black film formed on the surface of the coated parts by PVD coating technology. In the process of using PVD coating technology to prepare black titani...
