Shot Peening: Methods of Application of the Treatment and Induced Effects

Abstract

This editorial paper reports the features and main improvements that shot peening treatment can induce on machine elements. In addition to surface hardening, the compressive stresses at the surface allow to increase the fatigue resistance. Examples of applications of connecting rods, crankshafts and spur gears treatment are reported. The aim it produce high strength-to-mass ratio components, reduce weight and design eco-friendly machines and vehicles.
