Analysis of particle penetration into aluminum plate using underwater shock wave

Some techniques using underwater shock waves have been developed for several material processing applications: explosive welding, shock compaction, and shock synthesis. In this research, a new technique was developed for surface modification of an aluminum. plate. Diamond particles were accelerated by an underwater shock wave and penetrated into an aluminum plate, creating a surface coating of diamond on the aluminum plate. In the observation of the cross-section of the recovered Al-diamond composite, a rich diamond layer was confirmed at about 200 put depth. XRD and wear measurements were conducted for the recovered Al-diamond composite. We also report on the optical observation of the underwater shock wave in this paper.
