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 L value of the black film layer (that is, the lightness value) can only reach about 35 at best, and it is difficult to continue to reduce the L value of the film layer in order to obtain a purer black color.

Embodiment Construction

[0016] The vacuum coating part of the present invention can be an electronic device casing, and can also be a spectacle frame, a clock casing, a metal sanitary piece, and a construction piece.

[0017] see figure 1 , the vacuum coating member 10 of the preferred embodiment of the present invention includes a base 11 , a base layer 13 and a color layer 15 . The base layer 13 is directly combined with the matrix 11 , and the color layer 15 is formed on the surface of the base layer 13 .

[0018] The material of the substrate 11 can be metal, glass, ceramic or plastic.

[0019] The base layer 13 is formed between the base 11 and the color layer 15 to enhance the adhesion of the color layer 15 on the base 11 . The substrate layer 13 can be a chrome layer or other coatings that can provide adhesion. The thickness of the base layer 13 is about 0.01-0.1 μm. The color of the base layer 13 is preferably a color that does not affect the color of the color layer, such as light colors...

Abstract

The invention provides a vacuum coating part. The vacuum coating part comprises a matrix and a color layer formed on the matrix. The color layer is a chromium oxycarbide layer. An L*coordinate value of a chromaticity region shown on the color layer in a CIE LAB color system is in the range of 28 to 32, an a*coordinate value of the chromaticity region shown on the color layer in the CIE LAB color system is in the range of minus 1 to 1, and a b*coordinate value of the chromaticity region shown on the color layer in the CIE LAB color system is in the range of minus 1 to 1. The invention also provides a preparation method of the vacuum coating part.

Description

technical field [0001] The invention relates to a vacuum coating part and a preparation method thereof. Background technique [0002] 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 treatment is becoming more and more wider. However, the vacuum coating technology also has certain limitations. In the process of preparing a pure black film, it is easy to appear different colors, blue in black or red in black, which seriously affects the appearance of the black film. It has been reported that the L value (ie lightness value) of the black film layer can only reach about 35 at best, and it is difficult to continue to reduce the L value of the film layer in order to obtain a purer blac...
