Shot peen surface roughness
SpletShot peening is a cold working process in which the surface of a component is peened with small spherical balls called shots. The process induces plastic deformation on the surface, relieves surface tensile stresses and introduces beneficial compressive residual stresses. Splet24. okt. 2024 · Shot peening (also known as shot blasting) is a surface conditioning process carried out after various manufacturing processes. In simple terms it increases/improves the surface finish. Shot peening is done with the help of small balls which are streamed out in the form of a jet at very high velocity, accelerated and directed …
