Abstract:  
Water-jet peening and water-jet shot peening have the common feature of employing a jet of water. There are, however, important differences between the two processes. Water-jet peening has to impose a direct pressure high enough to generate surface plastic deformation. Water-jet shot peening, on the other hand, uses entrained high-velocity shot particles to generate the required surface plastic deformation. Figs.1 and 2 illustrate the essential differences between the corresponding impacting streams.
