Abstract

In the paper, using experimental data, models for geometric, mechanical, energetic, and temporal indicators of surface laser hardening are derived. A single-criteria and multi-criteria research was performed using DEFMOT. On this basis, three compromise solutions were obtained, which were rated in terms of performance and energy intensity. From them, a mode for the most rational use is recommended. It consists of V = 3.5 mm/s; P = 1450 W; FPP = 60 mm. The controlled indicators calculated according to the models are specified for it.
