Fundamentally, shot peening is a critical cold-working process that enhances the durability of metal parts. Specifically, it works by bombarding a metal surface with a high-velocity stream of shot under strictly controlled conditions. As a result, this impingement induces beneficial compressive stresses into the exposed surface layers of the component.
Shot Peening increases resistance to:
Fatigue failure, Corrosion fatigue, Hydrogen assisted cracking, Cavitation erosion, Stress corrosion cracking, Galling Fretting.
Shot Peening Helps with:
surface texturing, intergranular corrosion resistance, closing of porosity, testing of bond coatings, work hardening, increased strength, and increased durability.
This process significantly increases a part's resistance to several common failure modes, including fatigue failure, corrosion fatigue, and hydrogen-assisted cracking. Additionally, it provides protection against cavitation erosion, stress corrosion cracking, galling, and fretting.
Furthermore, shot peening provides a wide array of additional benefits. For instance, it is used for surface texturing, improving intergranular corrosion resistance, and closing porosity. Moreover, the process is highly effective for testing bond coatings, work hardening surfaces, and ultimately increasing overall strength and durability.
Shot Peening when applied on following components increases its service life
Pins – 400-1900%.
Shafts – 700 %
Helical springs – 3500 %
Gears – 30 %
Valves – 700 %
