Abstract Today, there is a sharp struggle for demanded and competitive products all over the world. The existing traditional production technologies have exhausted their possibilities. New technologies should be based on high energy technologies. One of such technologies is plasma technologies. Among the plasma technologies for hardening metal surfaces, the most suitable is the hardening technology using electric spark discharges. However, these technologies do not currently have process optimization. This article proposes one of the options for solving this problem by simulating the process of electrospark alloying of elements of refractory materials into the surface layer of samples of real parts of machines and mechanisms, which are models of these parts.
