The Impact of Advanced Shot Peening on Turbine Blades
Jan Smit
Senior Engineer
Shotoween Surface Technologies performs shot peening on metal components for the aviation industry. This process induces compressive stress in the surface layer of turbine blades and landing gear.
The resistance to metal fatigue and stress corrosion is significantly increased as a result. It is a critical surface treatment that extends the lifespan of essential parts and guarantees safety.
"Through controlled impact, we create a protective compressive layer that delays crack formation. It is the invisible force behind reliable performance."
The process uses small balls that are blasted at high speed against the metal surface. Each impact forms a microscopic 'crater' and causes plastic deformation, leading to the desired compressive stress.
