This article discusses specific interconnections between the strengthening mechanisms and the properties of the surface processed by laser shock waves. When such a technology is used, the strengthening effect is found to be provided by two main factors: the gradient microstructure caused by plastic deformation and the gradient depth distribution of implanted SiC particles. Three competing mechanisms affect the strengthening when a laser shock wave is applied to gradient reinforced layers: dispersion strengthening with SiC nanoparticles, grain refinement, and dislocation strengthening.
