Abstract

The material of surface layer absorbs the energy of laser and produces plasma, when the high power laser radiates the surface of material. The plasma blows up and produces an intense shock wave. When the surface of material is covered with a confining medium and an absorptive coating layer, the shock wave can be strengthened greatly. Therefore a huge momentum is exerted on the surface of material. There is a plastic deformation layer in the material when the shock stress exceeds the dynamic yield strength of material. Due to the residual compressive stress, the high density of dislocation in the plastic layer, the anti-fatigue life of material is prolonged.
