Abstract

The invention relates to a blue-black metal film and a preparation method and application thereof. The blue-black metal film comprises a metal base coat arranged on the surface of a base material, a transition layer, a color reference layer and a color adjusting layer, and the metal base coat is made of at least one of Cr and Ti; the transition layer is arranged on the metal base coat; the transition layer is made of TiCrCBN; the color reference layer is arranged on the transition layer, and the color reference layer is made of TiCBN; and the color adjusting layer is arranged on the color reference layer and is made of Cr. According to the blue-black metal film, through cooperation of the metal base coat, the transition layer, the color reference layer and the color adjusting layer, the hardness of the film layer is optimized, the wear resistance and corrosion resistance of the film are improved, and the comprehensive performance of the metal film is improved; and the metal film can still present uniform and stable blue black in a product with a curved surface such as a slotted hole, an included angle and a step, and can be widely applied to the field of high-end decorative coating.

Description

technical field [0001] The invention relates to the technical field of film materials, in particular to a blue-black metal film and its preparation method and application. Background technique [0002] The blue-black tone has visual characteristics such as stability, low-key, and rich sense of technology, so it is more favored by customers and the market. Usually, different proportions of TiAl alloy targets and N 2 Prepared by reactive magnetron sputtering, the color of the film is controlled by adjusting the ratio of Ti, Al, N and film thickness, which belongs to the interference type film. Using this method to prepare blue-black film has a wide range of color adjustment and easy color control, and is currently widely used. However, although the TiAlN film has a certain hardness and scratch resistance, the film will have obvious discoloration in the slots, angles, steps and other positions on the surface of the workpiece, and the anti-corrosion performance of the film is p...
