Abstract
The effect of electrospark and laser alloying with WC-, TiC-, and TiN-based electrodes on the physicomechanical and working properties of the high-speed steels R6M5 and R6M5K5 was investigated. Laser treatment of electrospark coatings based on refractory compounds increased hardness and heat resistance, and improved the contact properties of cutting tools in their interaction with the chip, thus increasing wear resistance. The optimal conditions of electrospark and laser alloying were determined.
