Shot Peened Surface Characterization Using 3D Metrology

Shot peening is a process by which a substrate is impacted with round metal, glass or ceramic beads, also known as shot, at a force intended to create plasticity on the surface. The characteristics present prior to and after the peening process provides vital information to
better the understanding and control of the process. Among many others, surface roughness
and dimple coverage area left by the shot, are of particular interest.
