Problems solved by technology

In the prior art, the surface treatment method of amorphous alloy using PVD technology has the defects of high cost, difficult operation and control, and unsatisfactory surface treatment effect.
In particular, the defect of higher cost leads to higher cost of products prepared by using amorphous alloys, thus affecting the wide application of amorphous alloys
In addition, when the amorphous alloy and aluminum alloy are combined to prepare products, the appearance of the amorphous alloy and aluminum alloy treated by PVD technology is quite different, which makes the color and texture of the product inconsistent, resulting in the final product not being beautiful. , which greatly affects the attractiveness of the product to consumers, and ultimately affects the sales of the product

Abstract

The invention relates to the technical field of amorphous alloy and in particular relates to a surface treatment method of amorphous alloy. The method comprises the following steps: 1, performing cold spraying, namely spraying an aluminum layer or an aluminum alloy layer to the surface of the amorphous alloy by adopting a cold spraying process to obtain a semi-finished product; 2, performing anodizing treatment, namely performing anodizing treatment on the aluminum layer or the aluminum alloy layer in the semi-finished product obtained in the step 1 to enable an aluminum oxide film to be formed on the surface the aluminum layer or the aluminum alloy layer to obtain a finished product. According to the method, the treated amorphous alloy product can be perfectly matched with an aluminum alloy product in appearance, and the appearance requirements of industrial design are met; moreover, compared with a PVD (physical vapor deposition) technology, the method has the characteristics that the appearance requirements can be well met on the basis of the advantage of low cost, and the application range of the amorphous alloy is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of amorphous alloys, in particular to a surface treatment method for amorphous alloys. Background technique [0002] Amorphous alloys have been applied in the fields of electronics, machinery, and chemical industry because of their excellent properties in terms of strength, hardness, toughness, wear resistance, corrosion resistance, soft magnetism, and superconductivity. [0003] At present, in the application process of amorphous alloys, in order to meet the appearance requirements of products, such as color requirements, industrial design or surface treatment is required. In the prior art, PVD technology (Physical Vapor Deposition) is mostly used for amorphous alloys to meet the color requirements of the appearance. In the prior art, surface treatment of amorphous alloys using PVD technology has the disadvantages of high cost, difficult operation and control, and unsatisfactory surface treatment effects. ...
