Problems solved by technology

[0002] At present, the color anti-corrosion decorative film is usually prepared in the following two ways: 1. The surface is electroplated with a metal film, and the metal includes chromium, titanium, aluminum, nickel, silver or gold; the decorative film prepared in this way has a bright metallic luster and is To a certain extent, it can improve the anti-corrosion performance of decorations, but its color is single, mostly golden yellow or silvery white, and it is difficult to obtain decorations of other colors; 2. The surface is coated with organic coatings; different organic coatings have different colors, After coating, a colorful decorative film can be obtained, and the anti-corrosion performance of the coating is also good, but organic coatings are often poisonous, and are easy to age so that the decorations fade and the anti-corrosion performance is weakened

Embodiment 1

[0038] In this embodiment, the substrate material is silicon, and the structure of the colored anti-corrosion decorative film on the surface of the silicon substrate consists of a titanium transition layer positioned on the silicon substrate and a tetrahedral amorphous carbon film positioned on the surface of the titanium transition layer. The thickness of the titanium transition layer is The thickness of the tetrahedral amorphous carbon film is 80nm, and the color anticorrosion decorative film is golden yellow.

[0039] The following is the preparation process of the above-mentioned colored anticorrosion decorative film:

[0040] (1) Put the silicon substrate into acetone or alcohol, clean it with an ultrasonic cleaner for 10-20 minutes, then rinse it with deionized water and dry it for later use;

[0041] (2) After fixing the substrate on the sample stage, place it on the turntable in the vacuum chamber of the cathode vacuum arc composite sputtering coating instrument, and eva...

Abstract

The invention discloses a colorful anticorrosion decorative film with controllable surface colors of a matrix and a preparation method thereof. The colorful anticorrosion decorative film is composed of a metal transition layer disposed in a matrix layer and a tetrahedron amorphous carbon film disposed on the surface of the metal transition layer, wherein the thickness of the tetrahedron amorphous carbon film is 10 nm-300 nm; and the colors of the colorful anticorrosion decorative film can be regulated by controlling the thickness of the tetrahedron amorphous carbon film to make the colorful anticorrosion decorative film present colors of prunosus, skyblue, golden yellow, grayish brown, silver grey, light green, etc. Compared with a conventional decorative film, the colorful anticorrosion decorative film has the characteristics of controllable colors, abundant colors, environmental protection, high hardness and excellent corrosion resistant performance, is not only a supplement and improvement for the field of the conventional decorative film, but also breaks through the common application field of the conventional tetrahedron amorphous carbon film, broadens the practical application field thereof, and has good application prospects.
