Shot peening

Shot peening is a mechanical process that involves bombarding the surface of a material, usually metal, with small spherical media called "shots." The purpose of shot peening is to improve the mechanical properties of the material, particularly its fatigue strength, ductility, and resistance to stress corrosion cracking. ### Process: 1. **Media Selection**: The shots used can be made of various materials, such as steel, glass, or ceramic, and come in different sizes.
