Abstract
Based on laser sources delivering intensities above 109 W/cm2 with pulse energies of several Joules and pulse widths of nanoseconds, laser shock processing (LSP) is being consolidating as an effective technology for the improvement of surface mechanical and corrosion resistance properties of metals. LSP is able of inducing a compression residual stresses field, improving the wear and fatigue resistance, due to slowing crack growth and stress corrosion cracking. First, the fundamentals of the process are briefly presented. A summary of the theoretical and computational methods developed for the predictive assessment of LSP, and of the practical results at laboratory scale on the application of the technique to different materials follow. A brief critical updated state-of-the-art on the improvements reported after using LSP is also presented, addressing mainly releasing the residual stresses after Friction Stir Welding.
