Shot peening is a cold working process that is used to produce a layer of compressive residual stress and modify the mechanical properties of metals and compounds. It involves impacting a surface with a shot (round particles of metal, glass or ceramic) with enough force to create plastic deformation. In machining, blasting is used to strengthen and relieve stress in components such as steel car crankshafts and connecting rods. In architecture it provides a silent finish to the metal.
The peening is similar to the sandblasting, except that it operates by the mechanism of plasticity rather than abrasion: each particle functions as a ball hammer. In practice, this means that the process removes less material and creates less dust.
Shot peening is the most economical and effective method of producing and making surface residual compression tensions to increase the life of treated metal parts. Shotblasting is also used to toughen work to improve wear characteristics, straighten distortions, texture the surface and create aerodynamic curvatures for aerospace designs. The increased strength of the treated parts allows lighter parts which exhibit high wear and fatigue resistance.
Engineered Abrasives® offers peening services performed under controlled conditions on our custom designed high performance peening machines. Our Shot Peening work services program provides the ability to analyze a particular part and improve its appearance and fatigue life for parts as diverse as gears, housings and axles.
