Abstract

The invention belongs to the technical field of alloy materials, and particularly relates to an alloy composite material. A first metal layer, a second metal layer, a third metal layer and a fourth metal layer are sequentially precipitated on the surface of a soft base material through a physical vapor deposition method. Compared with the prior art, the adhesive force between layers is good, the mechanical strength resistance is good, the preparing process is stable, the metal texture is high, the weather fastness is good, and a film is not likely to oxidization even when the film is exposed to air for a long time; and meanwhile, the alloy composite material further has the low and high frequency electromagnetism radiation-proof function and is suitable for batch production.

Description

technical field [0001] The invention belongs to the technical field of alloy materials, and in particular relates to an alloy composite material and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of electronics, aviation, and aerospace industries, a separate metal layer for preventing electromagnetic interference is no longer the only goal pursued by consumers. Alloy composite materials with layer structure gradually entered and attracted the public's attention. It has the function of low and high frequency electromagnetic radiation protection, which is favored by the public. [0003] However, the alloy composite material with layer structure in the prior art has the following defects: [0004] One is that the adhesion between layers is not good and it is easy to fall off; [0005] Second, the mechanical strength is not good; [0006] The third is that the preparation process is unstable, the weather resistance of ...
