SELECTED CERAMIC MOULDINGS AND PROCESS FOR SELECTING FAULTLESS CERAMIC MOULDINGS

摘要

The description relates to a process and device for producing focussed underwater shock waves by multiple simultaneous underwater spark discharge and focussing by means of confocal ellipsoids, in which a maximum pressure the GPa range is attained in the commun focus, and its use as a proof test for ceramic mouldings. The ceramic mouldings subjects to the proof test are initially faultless.
