preparation example Construction

[0038] A composite preparation method of an aluminum alloy and a magnesium alloy laminate, comprising the following steps:

[0039] ①Substrate and doubler board preparation: The size of the doubler board should be larger than the base board. According to the overall size of the doubler board, leave a space of 20mm to 100mm around the doubler board. 5mm groove, and leveling treatment and surface grinding and cleaning of the base plate and double board; the aforementioned base plate and double board are aluminum alloy and magnesium alloy, or magnesium alloy and aluminum alloy;

[0040] ② Preheating treatment of base plate and double plate: heat the base plate and double plate to 120 ℃ ~ 200 ℃ before explosive compounding, and carry out heat preservation treatment;

[0041] ③ Explosive composite foundation: use clay or fine sand for compaction, and lay 3mm to 8mm fiber composite board on the surface as the explosive composite base;

[0042] ④ Explosive preparation: Ammonium nitr...

Abstract

The invention relates to a compound preparation method of an aluminum alloy and magnesium alloy laminated plate, which is characterized by comprising the following steps: (1) preparation of a base plate and a compound plate: leaving an interval of 20-100mm at the circumference of the compound plate based on the overall size of the compound plate, machining grooves of 1-5mm in the compound plate corresponding to the edge of the base plate based on the thickness of the compound plate, and carrying out smoothing and surface polishing and cleaning on the base plate and the compound plate, wherein the size of the compound plate is greater than that of the base plate, and the base plate and the compound plate are respectively aluminum alloy and magnesium alloy or magnesium alloy and aluminum alloy; (2) pre-heating treatment of the base plate and the compound plate: prior to explosion cladding, heating the base plate and the compound plate to 120-200 DEG C, and preserving the temperature; (3) foundation of explosion cladding: compacting with clay or fine sand, laying a fiber compound plate of 3-8mm on the surface to act as an explosion cladding base; and (4) preparation of explosives. Thus, the overall explosion cladding process is simple and easy to operate, and the metal of the compound plate can obliquely collide the metal of the base plate at a high speed under the explosive load effect of the explosives, thereby firmly connecting the metal of the compound plate with the metal of the base plate.

Description

technical field [0001] The invention relates to a method for compounding aluminum alloy and magnesium alloy plates, belonging to the technical field of metal composite materials. Background technique [0002] Magnesium alloy has the characteristics of low density, high specific strength and specific stiffness, superior electromagnetic shielding and damping properties, good casting and cutting performance, and is a structural material with great development potential. However, due to the low standard electrode potential and poor corrosion resistance of magnesium, the application of magnesium alloys in the engineering field is greatly limited. Aluminum alloy has strong corrosion resistance in the natural state. If the magnesium alloy plate is wrapped between the aluminum alloy plates to avoid direct contact between the magnesium alloy and the environment, the problem of poor corrosion protection performance of the magnesium alloy can be effectively solved; At the same time, d...
