The article considers the influence of the radiation power W, the longitudinal feed Spr of the laser beam and the distance L from the protective glass of the laser focusing head to the workpiece on the PG-CP4 coating hardness which was applied to H12M steel by plasma and then subjected to laser treatment. A multi-factor model is established that relates the PG-CP4 coating hardness to the input process factors and allows you to quickly assign a laser treatment mode and to control it in order to improve the quality of the processed surface layer. Increasing W, Spr and L leads to a increase in the HV parameter. The longitudinal feed Spr of the laser beam has the greatest effect on the surface layer hardness, then followed the distance L and radiation power W. The research results are relevant for manufacturing enterprises that implement laser processing processes of materials and design organizations that develop modern laser equipment.
