Description

technical field [0001] The invention belongs to the technical field of processing and manufacturing non-ferrous metal material plates, and in particular relates to an explosive welding forming method of a titanium-pure aluminum-aluminum alloy composite plate. Background technique [0002] Titanium-pure aluminum-aluminum alloy explosively welded composite plate is a new type of three-layer metal structure composite material, which combines the advantages of titanium, aluminum and aluminum alloy. It not only has the excellent corrosion resistance of titanium, but also has the low density of aluminum, It has the advantages of good electrical and thermal conductivity, easy processing and molding, and low price. The application of this composite board to the skin of aircraft equipment such as aerospace not only solves the problem that the steel aircraft skin is easily corroded in the past, but also solves the light weight, high corrosion resistance, high wear resistance and high ...

AI Technical Summary

Problems solved by technology

However, due to the different physical and chemical properties of titanium and aluminum, the composite method is difficult

Explosive welding composite process is through the instantaneous high pressure and high temperature action of explosive detonation wave to push the double plate to act on the substrate to make it achieve solid phase connection and metallurgical combination. Explosive welding is suitable for the connection of the same or dissimilar metals; explosive composite plate The size and shape specifications of the explosive molding are not limited by the equipment; the explosively formed composite material has high bonding strength and reprocessing performance, but there are still many disadvantages in the explosive forming process, which needs further improvement
