Abstract
Laser irradiation of the electrospark alloyed surface of high-speed steel produced remelting of the surface layer and formation of a broad structure transition zone. This optimized the gradient of properties at the surface. Laser treatment of the electrospark coatings produced tensile stresses in the surface layers, whose magnitude and distribution were dependent on the treatment conditions, as well as the physico-chemical interaction of the refractory compound with molten steel in the liquid pool formed by irradiation.
