    Proven technology of Laser Shock Peening (LSP) process for the cavitation erosion resistance improvement

  • Original language description

    Development of the Laser Shock Peening (LSP) process which when applied can improve the resistance to the cavitation erosion in pumps. The basic principle of the LSP technology The high-energy laser after passing the confining medium is forming a high-pressure plasma. By this principle, shock waves are generated and they are plastically deforming the material and inducing deep compressed residual stresses. In such a principle, certain mechanical properties of the material are changed and typical improvements are prolonged fatigue life, prevention of the corrosion stress cracking, or wear resistance improvement. Additionally, the hardness can be improved as well. Cavitation erosion is a fatigue driven phenomenon, and by applying the LSP the cavitation erosion can be reduced and slowed down. The LSP was applied to the blades which in the end form the pump impeller. The blades are made of stainless steel 304 (1.4306) and stainless steel 321 (1.4541).
