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 Al/ZrO2 joint. © 1998, The Japan Society of High Pressure Science and Technology.
