[0002] Magnesium alloy has the characteristics of light specific gravity, high specific strength, easy recycling, and rich reserves of resources. It is a green engineering structural material and has a wide range of application values ​​in the fields of automobile, aerospace, and electronics industries. However, magnesium alloys have poor corrosion resistance, strength, The low hardness has greatly limited the application of magnesium alloys; in order to improve the strength, hardness and corrosion resistance of magnesium alloys and broaden their application fields, magnesium alloys are often combined with other metals with good corrosion resistance and high strength. , made of composite panels to expand its application range
[0003] At present, there are two ways to process the magnesium

Embodiment Construction

[0072] The present invention will be further described below in conjunction with accompanying drawing:

[0073] figure 1 As shown, it is the state diagram of the explosive welding of the magnesium-aluminum-titanium alloy composite plate. The position of each part must be correct, prepared according to the quantity, and operated in sequence.

[0074] The amount of chemical substances used in explosive forming welding is determined according to a preset range, with grams, millimeters, and milliliters as measurement units.

[0075] The explosive welding of the magnesium-aluminum-titanium alloy composite plate is carried out on the open soil ground, and the magnesium alloy substrate, the gap column, the aluminum alloy intermediate plate, the gap column, the titanium alloy composite plate, and the butter buffer protection are placed on the sand foundation. Layer, explosive frame, ammonium fuel oil explosive, electric detonator, shielded cable, electric detonator detonator are comp...
