Shot Peening
Advanced Surface Treatment for Turbine Blades
By: Eng. Klaas Visser
Shotoween Surface Technologies performs 'shot peening' (shot blasting) on critical metal components for the aviation industry. This advanced process induces controlled compressive stress in the surface layer, leading to a significant increase in lifespan.
The Process in Detail
During shot peening, small balls are blasted onto the metal surface at high speed. Each impact creates a microscopic 'crater' and plastic deformation. The interplay of thousands of these impacts results in a uniform compressive stress layer.
Key Benefits:
- Increased resistance to metal fatigue by up to 300%.
- Improved protection against stress corrosion in aggressive environments.
- Extended operational lifespan of turbine blades and landing gear.
- Reduction of crack growth in existing microcracks.
Application Materials
Our treatment is suitable for a wide range of high-quality alloys, including titanium, nickel-based superalloys, and high-strength steels used in modern aviation.
