Shot peening

Shot peening is a process used to enhance the durability of metal parts by bombarding their surface with small, round particles called shots. When these shots impact the metal, they create tiny dents and compress the surface layer, which increases its strength and resistance to cracking, fatigue, and corrosion. This technique is commonly applied to components like aircraft wings, automotive parts, and turbines to extend their lifespan and improve performance, especially under cyclic stress. Overall, shot peening is a controlled method to improve the structural integrity of metal objects through surface enhancement.
