Laser shock equipment-ShangHai RunQia Electronics Technology Co.,Ltd.

Laser shock peening (LSP) involves irradiating the metal surface with a short pulse (≤20ns) and high peak power density laser, causing the protective absorption coating on the surface to absorb the laser energy and undergo explosive vaporization. This generates a high-pressure plasma shock wave. By utilizing the mechanical effect of the shock wave, the microstructure of the surface material is altered, leaving residual compressive stress at greater depths, thereby enhancing the fatigue resistance, impact damage resistance, and fretting wear resistance of the metal material.

Laser shock peening applications

1. Aerospace Industry

Laser shock peening (LSP) technology is used to enhance the fatigue resistance, foreign object damage resistance, and fretting wear resistance of critical components in aero-engines, such as compressor blades, turbine blades, integral blisk, disk shafts, and ducts.
