Definition

A mechanical surface-treatment process that repeatedly impacts a component's surface with small spherical media (shots) to introduce a controlled layer of compressive residual stresses and modify surface topology, thereby reducing the tendency for tensile-stress-driven crack initiation and early fatigue failure.
