Abstract:  
In this paper, we focused on the particle velocities of fine particle peening process (FPP) and measured them by a high-speed camera. Also, we developed the theoretical model of particle motions with the effect of jet flow and calculated the particle velocities after spouting from the nozzle. Then, we compared the experimental results with the calculated results, and those agreed well each other. It is concluded that the particle velocity can be estimated by our prposed model and it is helpful information for understanding the surface modification in fine particle peening (FPP) process.
