Wet shot peening

Controlled shot peening is a sensitive technique, based on the structural transformation of materials.


Principle

The process consists of putting mechanical parts under superficial compression by the projection of small steel, glass or ceramic beads.

Applied on the entire surface to be treated or only on certain areas, this microbead blasting operation creates a compressed area which increases the surface hardness of the parts concerned and decreases their deterioration due to fatigue.

 

Applications

  • Structural parts made of aluminium or titanium alloy
  • Treatment carried out before anodizing for aluminium alloys
