Shot peening is a process where the spherical abrasive is tossed at high speed over a metallic surface of machine components to remove its impurities. The impact of the granules over the metal changes the surface.
During the process, the metal is compacted due to the granule pressure, which offsets the compressive stress acting over the part. The equipment crack risk by stress ends up being reduced.
According to some studies, shot peening can increase component life in service in up to 1,300%. The reduction of tensile stress on the surface can reduce equipment fatigue in 560%. Among the component that can have life in service increased: gearboxes, crankshafts, blast wheel blades or other blast wheel components.
