Abstract
The effect of electrospark and laser allaying with WC-, WC-, and TiN-b ased electrodes on the physicomechanical and working properties of the high-speed steels R6M5 and R6M5K5 was investigated. Laser treatment o f electrospark coatings based on refractory compounds increased hardne ss and heat resistance, and improved the contact properties of cutting tools in their interaction with the chip, thus increasing wear resist ance. The optimal conditions of electrospark and laser alloying were d etermined.
