Special Processes

Shot Peening

Shot peening is a cold working process used to produce a compressive residual stress layer and modify the mechanical properties of metals and composites. It entails striking a surface with shot (round metallic, glass, or ceramic particles) with force sufficient to create plastic deformation.

Cold Compression Rolling

This is the process of strengthening the materials by changing its shape without using heat.

Nickel Sheet

The Leading Edge from composite propellers are susceptible to damage from foreign object damage.

Aerohélice team is trained for repair or replacement of this critical composite blade component.

Glass Bead Peening

Glass shot conforming to this specification is intended for use in peening of metal surfaces to impart compressive stresses, thereby increasing resistance to fatigue and stress-corrosion cracking. Generally, glass shot may be used where:

  • Very low intensities are required because glass shot is available in smaller sizes than other media.
  • Very small, under 0.015 inch (0.38 mm) radii or narrow slots are intended to be peened. – Ferrous contamination of peening media is undesirable.
