| Abstract | ||
| In this work, results of spot hardening in low-carbon steel by using a pulsed Nd:YAG laser are presented. These results include determination of hardening depth, diameter of hardened spot, aspect ratio and heat-affected zone width with varying laser energy density. In order to determine the effect of irradiation profile on the overall achievable hardness, the profiles of overlapping, adjacent and separated hardened spots are compared and the percent coverage of the workpiece as a function of the laser-hardened spot dimensions. | ||
