Shot peening is a cold working process that is used for developing a compressive layer and helps in modifying the mechanical properties of a metal. We use shot peening media as a tool to operate on this technology. It should be spherical and broken and uneven particle of this media that produce harmful effects.
The media must possess hardness in the part that is used for peening and should also be conditioned to the limited size, thus preventing the reduction of compressive residual stress. Moreover, these shot peening media should be dry, clean, and free from dust to reduce the damping effect and compressive residual stress. Furthermore, it also helps in preventing the depth of compressive stress layer & unacceptable contamination.
