Shot peening - Wikipedia

Shot peening is a cold working process used to produce a compressive residual stress layer and modify the mechanical properties of metals and composit It entails striking a surface with shot (round metallic, glass, or ceramic particles) with force sufficient to create plastic deformation In machining, shot peening is used to strengthen and relieve stress in components like steel ....

Shot Peening - an overview | ScienceDirect Topics

Shot peening induces roughness on the surface that is linearly proportional to the velocity/intensity of the shot As a general rule, larger shot size results in greater roughness at lower velocities, 10 as shown in Figure 1, where a comparison is made between steel shot (ss230, ss110, and s70) and glass beads (100, 50, 35 µm GB)The roughness of the surface is the side effect of the shot ....
