Now Playing: Shot Peening Review
  • Description:  Shot peening is a cold working process used to produce a compressive residual stress layer and modify mechanical properties of metals. It entails impacting a surface with shot (round metallic, glass, or ceramic particles) with force sufficient to create plastic deformation.[1] It is similar to sandblasting, except that it operates by the mechanism of plasticity rather than abrasion each particle functions as a ball-peen hammer. In practice, this means that less material is removed by the process, and less dust created.
