Laser Shock Processing of Surface Copperize on Arc-Meshes Gear

This paper presents surface modifications of aluminum-alloy induced by laser-shock processing (LSP). In the first part, the basic principles are discussed to provide an overview of the physical processes involved in laser shock processing, and to introduce pressure loadings generated by different laser generators. In the second part, emphases are given to the effects of laser intensity, target material, laser pulse duration and laser wavelength, and uniform and localized modeling of fatigue behavior after LSP. In the third part,experimental results are given to show the laser-induced pure mechanical effects on aluminum-alloy by using LSP.
