Problems solved by technology

[0004] However, the problem with clad metal plates is that the combination of layers using explosive welding requires a lot of energy, which is highly dangerous and difficult to achieve mass production. Improve production yield
In addition, the base layer and the outer layer are only bonded by solder, and if it is applied in a field subject to shear force, it is very easy to cause the base layer and the outer layer to slip and detach.
Furthermore, it uses solder to join by explosive welding, which is not suitable for some specific metals (such as magnesium or magnesium alloys), and needs to be improved urgently.

Embodiment Construction

[0056] The detailed description and technical content of the present invention are described below with the accompanying drawings, but the attached drawings are only for reference and illustration, and are not used to limit the present invention.

[0057] see figure 1 and Figure 5 As shown, the invention provides a kind of preparation method of composite metal, and its step comprises:

[0058] a) A surface 11 of a first metal body 10 is formed with a plurality of protrusions 13, a plurality of concave grooves 14 formed between each of the protrusions 13, and a concave groove 131 formed in each of the protrusions 13; please refer to figure 2 and image 3 As shown, the first metal body 10 in this step can be a plate or cylinder made of a metal material with high hardness such as copper alloy or stainless steel. The first metal body 10 has a first surface 11 (or simply surface) and a second surface 12 formed behind the first surface 11. Wherein the forming processing can b...

Abstract

The invention discloses a composite metal manufacturing method and a composite metal structure, wherein the composite metal structure includes a first metal body and a second metal body, the first metal body has a surface, and the surface is formed with a plurality of convex bodies and formed between the convex bodies There are many concave grooves in between, and each convex body is respectively provided with a concave groove, the concave groove has a root width and a top width, and the root width is greater than the top width; the hardness of the second metal body is smaller than that of the first metal body, and the second metal body is pressed It is connected to the surface of the first metal body and embedded and combined with each convex body, each concave groove and each concave groove. Thereby, the bonding firmness of the two metal bodies can be improved, the process can be simplified and the manufacturing time can be shortened.

Description

technical field [0001] The invention relates to a joining technology of composite materials, in particular to a composite metal and a manufacturing method thereof. Background technique [0002] With the continuous progress and development of science and technology, the application of composite materials in various products has become increasingly common, such as casings and mechanism accessories of mobile phones, tablet computers, notebook computers, etc.; fan blades, automobile and motorcycle parts, medical equipment , home appliance shells or spare parts, helmets; automobile and motorcycle exterior panels and internal structural accessories, aircraft internal and external accessories, propellers, general hull structural parts, military helmets, bulletproof parts, sanitary equipment, building materials, etc. The list goes on and on. The finished products produced not only have many advantages such as light weight, thin profile, and good appearance and texture, but also can ...
