Abstract

The traditional tempering methods induce strong stresses in the tried elements. It is necessary however for numerous industrial applications to maintain the properties of the material in the interior of the bulk at the same time as an elevated superficial hardness. Laser tempering achieves notable increments of hardness whilst modification of the surface is kept to a minimum. The control of the parameters that participate in the process, combined with the characteristics of the material, enable a specific hard layer to be obtained. Two steels were treated, AISI 1045 and AISI 1020, with a laser of CO? of 1700 W of capacity. In this paper, we reveal the working method, and the influence of the different parameters of the laser machining a
