Paper Abstract

The contribution deals with studies on residual stresses and microhardness of laser hardened carbon steel surfaces. Laser hardening can greatly improve the wear and fatigue properties by inducing a hardened and compressed surface layer. Residual stress distribution across the hardened tracks were measured by means of x-ray diffraction. It has been found that compressive stresses exist in the hardened zone of all the specimens studied. The microhardness increased by as much as 350%.
