Shot peening strengthens aircraft components by creating compressive forces on the surface. It enhances metal fatigue strength, reduces the risk of cracking, and extends operational life across structural and propulsion components.
This precision technique projects small, rounded particles at high velocity onto the metal surface. Instead of cutting or removing material, it slightly reshapes the surface layer, introducing beneficial stress that enhances durability. We perform this controlled impact method with AS9100-compliant automation to ensure uniform coverage and consistent performance.
No measurable material removal occurs, maintaining each component’s precise geometry and tolerance.
Forms a protective layer on stainless steel, ensuring long-term resistance in harsh aerospace environments.
Extends parts’ lifespan by minimising corrosion and oxidation, reducing maintenance and replacement frequency.
Passivation doesn’t alter dimensional tolerances, maintaining the ±0.005mm precision required for aerospace parts.
Essential for mission-critical components like connectors and housing that are exposed to corrosive conditions.
Enhances adhesion for coatings like alodine, ensuring superior finishing and consistent performance
