Laser Peening Applications

Improve Performance and Reliability

As manufacturing costs increase and new designs become more expensive, service life extentions are a cost-effective method to maximize the value and efficiency of available materials. LSP Technologies has a legacy of enhancing critical components through collaborative partnerships across many industries. These partnerships have led to decreased costs for customers along with safer and more reliable components.

Aviation Applications

  • Engine components
  • Turbine, fan, and compressor blades
  • Bulkheads, wing attachments, flight control mechanisms, wheels
  • Brakes, landing gear
  • Welded titanium and aluminum components for improved reliability
  • Welded aging aircraft parts for improved reliability
  • Fasteners and fastener holes to combat fatigue, fretting fatigue and stress corrosion cracking
  • Cost-effective, high reliability castings to replace forgings
  • Mobile laser peening for deployment at repair depots for treatment of large structures and detection of exfoliation corrosion

Power Generation

Laser peening has become a widely adopted surface enhancement solution for turbine engine components in land-based gas and steam turbine generators. The process has also been adopted to treat weldments and containment vessels for nuclear power systems.

Automotive Applications

Laser peening can be applied to improve material characteristics and performance of many automotive and truck parts including transmission gears and axles, crankshafts, rotating engine parts, and impellers. Laser peening applications have been shown to provide increased reliability, improved fuel economy, weight reduction, and enhanced cracking resistance.

Applications for the Army

Within the U.S. Army, numerous opportunities exist for laser peening enhancement of fatigue-prone helicopter parts such as transmission gears and other drive train components. Laser peening will enable the development of lightweight drive trains capable of higher horsepower loads than present generation helicopters. Laser peening can also improve the performance and reliability of rapid cycling firearms and artillery, as well as toughen support systems and vehicle components in tanks and armored vehicles.

Applications for the Air Force

Laser peening has already been incorporated into several designs currently employed by the U.S. Air Force. Additional potential applications include laser peening for stress relief of nuclear propulsion system parts such as tube/sheet welded assemblies for improved resistance to stress corrosion cracking (SCC) and crevice corrosion. Other candidates include fatigue-prone catapult and tail-hook arrest mechanisms, ship drive gears and bearings, and welded vehicle or HUMVEE components that are susceptible to stress corrosion cracking.

Medical applications

Medical Applications for Laser Peening include treatment of orthopedic implants to improve the fatigue performance of hip and knee replacement joints and spinal fixation devices.

Tooling and Manufacturing Applications

Cold pilgering or tube reducing, is a room-temperature, cyclic metal forming process in which metal tubing is reduced in cross section by a combination of wall thinning and diameter reduction. The pilgering process produces seamless, high-strength tubing used in critical applications such as aircraft hydraulic lines, where high fatigue strength is necessary. Additional applications for pilgered tubes include commercial heat exchangers, zirconium nuclear fuel cladding, and aircraft engines to name a few. Pilger and other tooling dies, as well as well drilling bits and many other machine tools have been laser peened and benefited from the improvement in fatigue life and strength.
