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.

整体脉冲激光淬火后单硬质合金的耐磨性增加

摘要

在本文中，我们研究了体脉冲激光淬火（BPLH）对在粗加工条件下运行的单碳化硬质合金的耐磨性提高的影响。已确定钴的β→α的反向相变，其强度取决于所选的处理模式（激光脉冲的能量和持续时间，激光束直径，从照射位置到主切削刃的距离）在BPLH效应下在硬质合金中观察到。显示出BPLH可提高单硬质合金的耐磨性。
