Abstract

The invention provides an amorphous alloy colored film with adjustable colors and a preparation method thereof and belongs to the amorphous field. The colored film comprises, by atomic percent, 0-20%of Al, 10-30% of Cu, 0-10% of Fe, 0-10% of Ag, 0-20% of Ni, 25-50% of N and the balance Zr. One or more of silver, gray, golden yellow, green, yellow, purple, orange, blue and red are displayed when the film is put on the surface of a metal substrate. The preparation method of the film comprises the steps of 1, preparing a single Zr-based alloy target material; 2, selecting a metal material or a non-transparent plastic material as the substrate; and 3, conducting a magnetron sputtering reaction in mixed atmosphere of argon gas and nitrogen gas. The amorphous alloy colored film prepared throughthe method is high in hardness, corrosion resistance and scratch resistance; good bonding force is achieved when the film is bonded with the metal substrate; and the film can be deposited on varioustypes of substrates and surfaces of devices in large areas.

Description

technical field [0001] The invention belongs to the field of material surface treatment and thin film technology, and more specifically relates to a high-hardness amorphous alloy colored thin film with adjustable color and a method for preparing the colored thin film. Background technique [0002] High-hardness colored thin film materials have broad application prospects in decorations, optical devices and IT industries. Traditional colored thin film materials adopt the following methods to prepare: 1) surface electroplating metal film, metal includes chromium, titanium, aluminum, nickel, silver or gold etc.; This decorative film has high hardness and bright metallic luster, but its color is single, It is mostly golden yellow or silvery white, and it is difficult to obtain other colors; 2) Through the superposition of multi-layer films, interference effects produce different colors (such as the literature Nanometreoptical coatings based on strong interference effects in high...
