Ultrasonic Shot Peening technology allows the use of high quality media. Quality madia combined to the real-time control of parameters, ensures a repeatable and efficient treatment. Ultrasonic Shot Peening (USP) induces a low roughness and a better surface quality compared to the conventional shot peening. This has a direct influence on fatigue-life enhancement and prevent Stress Corrosion Cracking.
Shot Peening is a process used to produce a beneficial compressive residual stress layer and modify mechanical properties of metals. Shot peening entails impacting a surface with high velocity shot (round metallic, glass or ceramic beads) with force sufficient to create plastic deformation: each bead functions as a tiny peening hammer
