Multi-Criteria Research of Geometric, Mechanical, Energetic Andtemporal Indicators Depending on Laser Hardening Parameters

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.
