Abstract
In this paper, we study the effect of bulk pulse-laser hardening (BPLH) on the increase in the abrasive wear resistance of single-carbide hard alloys operating under roughing conditions. It was established that reverse β → α phase transitions of cobalt, the intensity of which depends on the selected processing modes (the energy and duration of the laser pulse, the laser beam diameter, the distance from the irradiation place to the main cutting edge) are observed in hard alloys under the BPLH effect. The BPLH is shown increase the wear resistance of single-carbide hard alloys.
