Abstract
Profiting by the availability of powerful laser sources able to provide intensities exceeding the GW/cm2 level, an intense research effort is under course aiming to develop Laser Shock Processing (LSP) as a leading industrial technology for materials surface properties improvement amenable to production engineering. In the same line, the authors have undertaken a research program in the line of practical development of the LSP technique at an experimental level, aiming its integral assessment from an interrelated theoretical and experimental point of view. In the present paper, experimental results on the residual stress profiles and associated surface properties modification successfully reached in typical materials (concretely Al alloys used in aerospatial applications) under different LSP irradiation conditions are presented. In particular, the analysis of the residual stress profiles obtained under different irradiation strategies and the evaluation of the corresponding induced surface properties as roughness, microhardness and wear resistance are presented. The test piece geometry used for the presented analyses is always intended to allow the comparison of different laser pulse overlapping factors and, especially, the comparison of the experimental measurement results with the numerical results obtained through the numerical simulation system developed by the authors, a possibility remarkably important from the point of view of industrial implementation.
