Shot peening, also known as peen forming, is a treatment used in particular in the aeronautical and mechanical sector to increase fatigue resistance of mechanical elements.
It essentially consists of a cold deformation, obtained by means of the impact on the part of metallic and non-metallic spheres. The process is aimed at inducing a field of residual compression forces in the surface layer of the treated piece.
No doubt the quality of the “tool” shot has a fundamental importance for a good outcome of the treatment.
Owing to the particularity of the process Techma offers technical consultancy concerning the most suitable material and shot-peening paramaters.
Techma proposes customers a wide range of shots for shot peening:
- cast spherical steel shot
- run-in pin steel shot
- run-in pin stainless steel shot
- glass microspheres
- ceramic microspheres
