Abstract

The invention discloses a magnesium-aluminum composite board and a method for manufacturing the same. The magnesium-aluminum composite board comprises at least one layer of magnesium or magnesium alloy plate and at least one layer of aluminum or aluminum alloy plate which are cast together by vacuum die-casting, and at least one two-layer joint surface which is provided with a mutually occlusive zigzag structure, namely the magnesium-aluminum composite board consists of a magnesium plate and an aluminum plate, or the magnesium alloy plate and the aluminum plate, or the magnesium plate and the aluminum alloy plate, or the magnesium alloy plate and the aluminum alloy plate by vacuum die-casting, and can be a structure with two layers, three layers or more than three layers. The method for manufacturing the composite board comprises the following steps: preheating a manufactured aluminum or aluminum alloy plate finished product as an insert of a die to certain temperature, and then putting the insert into a magnesium or magnesium alloy vacuumized die; matching the die in a vacuum pressure casting machine; pouring the molten magnesium or magnesium alloy molten; performing vacuumizing injection; and finally forming the magnesium-aluminum composite board. The joint surface of the composite board is provided with the mutually occlusive zigzag structure so that the layers are closely connected with each other sequentially and the combined strength is higher.

Description

technical field [0001] The invention relates to a composite plate and a manufacturing method thereof, in particular to a composite plate composed of magnesium or magnesium alloy plates and aluminum or aluminum alloy plates and a manufacturing method thereof. Background technique [0002] Magnesium is the lightest metal structure material, rich in resources, easy to prepare, excellent in electromagnetic shielding performance, and easy to recycle. Many excellent properties make magnesium have a wide application value in many fields, such as automobile, aerospace, IT industry, etc., and because of its good biocompatibility, it has the possibility to be used as biomaterials. With the gradual expansion of the application of magnesium and magnesium alloys in the fields of auto parts, electronic products and aerospace, it is expected to gradually replace aluminum and aluminum alloy parts. In some special occasions, it is also required to weld magnesium and aluminum into composite ...
