What is Laser Peening?

Laser peening is a surface enhancement method for extending the life of metal components. Laser peening improves fatigue life and damage tolerance by imparting deep compressive residual stresses that inhibit crack propagation. The compressive residual stresses generated by laser peening typically extend five to ten times deeper than those produced by shot peening, ensuring more robust components with longer service lifetimes.

Enhanced Resistance to Failure

Laser peening has been proven to significantly extend the fatigue life of metal parts by providing enhanced resistance to common failure mechanisms:

  • Foreign Object Damage
  • Fretting Fatigue
  • High-Cycle Fatigue
  • Corrosion Fatigue
  • Stress Corrosion Cracking
  • Erosion
  • Cavitation
  • Hydrogen Embrittlement
  • Creep Deformation

Superior Part Performance

Laser peening has become a widely-adopted process for enhancing the fatigue resistance of high-value metal components. Laser peening extends component fatigue lifetimes and has proven applications accross a broad range of industries. Laser peening has demonstrated material improvements in a variety of metals, including:

  • Titanium Alloys
  • Steel Alloys
  • Stainless Steels
  • Nickel Alloys
  • Aluminum Alloys
  • Carburized and Nitrided Steels

Laser peening is often referred to as laser shock peening (LSP) or laser shock processing because the laser generates a powerful shockwave that plastically deforms the material. Read more about How Laser Peening Works.
