Manufacturing Process
BACLAD™ explosively bonded metal composites are produced by metallurgically bonding two or more similar or dissimilar metals with the energy generated by explosion.
No chemical agents or heat are applied in this process.

1.Setting
Cladding metal is positioned above base metal
with a specific clearance in between, and
explosives are charged on the surface of the
cladding metal.
|
|
 |
2.Detonation
The explosives are detonated, and as the detonation front moves across the cladding metal, the energy generated by the explosion presses the cladding metal onto the base metal at an extremely high speed, fluidizing the collision front of both metals.
This fluidized metal forms a “metal jet”, as oxides, nitrides, and absorbed gases are removed from the bonding surfaces, exposing clean metal surfaces to collide.

3.Explosion Bonding
Activated surfaces of the metals are brought together with such force that the surface molecules are brought close enough to bond together by interatomic attraction.
The detonation front travels so quickly that bonding
is completed before heat transmission is able to occur.
Explosion bonding is characterized by a wave in the bonded interface. |
