Explosive Welding of a Thin Metallic Plate onto a Ceramic Plate Using Underwater Shock Wave

Abstract

Thin metallic plate was welded onto a ceramic plate using regulated underwater shock wave. The thin metallic plate was accelerated about 900 m/s by underwater shock wave and collided with ceramic plates, such as the ZrO₂ ceramic plate. Bonding was achieved through intensive deformation at the collision point, but cracks were normally generated in the ceramic plate. The use of a cover plate with the metallic plate and other devices such as momentum traps was effective in eliminating cracks in the AI/ZrO₂ joint.
