A process where small round particles, usually metallic, ceramic, or glass, are impacted against the surface of a metallic part at high enough velocity to cause plastic deformation on the surface. This results in compressive residual stress, strengthening the surface.
As with media blasting, compressed air is used to deliver the particles. However, instead of removing material to modify the surface finish, shot peening is used to strengthen the surface.
