Explosive Welding of Molybdenum/Copper Using Underwater Shock Wave

摘要

In this research, surface modification of copper with molybdenum was made using explosive welding technique. The underwater shock waves derived from the detonation of explosives was used to bond thin films of molybdenum on copper. Visual observation shows a sound joining of Mo/Cu. Microstructural characterization reveals the bonding interface with a clear wave formation between the participant metals. A clear wavy interface is formed when the weldable conditions lie in the weldability window. When the weldable conditions lie near the right limit or lower limit, a jet trapped region was formed.
