“…iode lasers are highly efficient and compact light sources and as such they are used in a large range of applications [1], [2]. In contrast to lasers based on specific atomic transitions like solid state or gas lasers, diode laser material engineering allows the generation of light in a large part of the optical spectrum [3].…”

“…To control laser hardening operation it is necessary to keep surface temperature constant. Surface temperature control can be done adjusting beam power in a close loop with surface temperature, which can be easily measured by bi-chromatic pyrometry [1] or IR thermography [2]. The main drawback in laser hardening is that the heat affected zone or hardened layer, cannot be measured without destructive test.…”

The main disadvantage for industrial application of new processes based on laser surface treatments, such as laser hardening, quenching or precipitation hardening, is the prior experimentation needed to determinate the optimum conditions for processes. The presented work is focused on the development of a tool based on a semi-empirical model to predict accurately the thermal field and thickness of the head affected zone in laser surface treatments in order to avoid the previous experimental setups of this processes. The conventional thermal models are focused on solving the differential equation of temperature field, considering the laser as heat source and thermal properties of each material. However, during the rapid heating treatment processes of metal surfaces are some unknown heat sinks such us metallurgical transformations or a changeable material absortivity that must be taken into account. The model has been adjusted and validated with experimental data for AISI 1045.
