Abstract:The paper deals with the development of a new hybrid technology – 3D laser work hardening which consists in the integration of laser shock treatment (laser work hardening) into the process of selective laser melting. The technology offered will allow obtaining an area of compressing residual stresses in a near surface layer and achieving the improvement of mechanical and fatigue properties of parts manufactured. In this paper the aluminum alloy samples were processed with laser work hardening with the use of u… Show more
