Laser Shock Peening | LSP

Laser Shock Peening (LSP) can significantly extend metal components service life in all major industries. It is especially effective for components that have to withstand cyclic loading and aggressive environments where stress corrosion cracking may occur. The main advantages of LSP are generation of deep compressive stresses and ability to target specific often hard-to-reach areas and complex geometries.

Thanks to our professional LSP station and training by professor S. R. Mannava, one of the founders of LSP technology, our R&D team is able to design proof of concept experiments and develop application processes for LSP according to your specific needs. To optimize the residual state profile, we use modern analytical devices as well as state-of-the-art laser system Bivoj.

LSP Benefits

  • Cold working process that delivers residual stresses up to 2mm in depth.
  • Precise control of the laser impact location.
  • Treatment of hard to reach areas.
  • Increases resistance to fatigue, fretting fatigue, stress corrosion cracking and reduces wear & tear, thus preventing costly failures and downtime.
  • Eco-friendly process (creates less waste material, uses less consumables, components last longer).
  • Strain hardening, grain refinement.
  • Reduces tensile stresses and improves microstructure of 3D printed parts.
  • Allows light weighting.
  • Applicable to aluminium alloys | structural and alloy steels | titanium alloys | nickel alloys.

Successful cooperation is always about people. And those from the LSP application group are simply perfect. I consider almost two years of cooperation with a young team led by Jan Brajer to be one of the best for my entire 20 years of experience in the PVD coating industry. With its concept, the HiLASE Centre goes beyond the standard academic structures I have known so far. Even with a technology giant, highly practical applications such as increasing the life of a forging die by applying LSP can be successfully addressed. The mutual cooperation will continue within the international Delta2 project.
