The article discusses the importance and relevance of the problem of controlling the quality of surface layers of parts. An analysis of the dependences of the thickness of the hardened layer of steel 20 and steel 40 and their microhardness on the technological parameters of electric-spark alloying (ESA) during nitriding using special technological saturating media (STSM) is presented. As established, with the existing technology, the thickness of the hardened layer consisting of the ‘white’ layer and the diffusion zone, as well as the microhardness of the surface, increase with increasing discharge energy. These parameters also increase with an increase in the processing time of a certain plane (ESA labour intensity) and a decrease in its reciprocal value, i.e., the area treated per unit time (alloying productivity). As a result of the research, mathematical models of the dependence of surface quality parameters during ESA nitriding using STSM (equation of hardened layer thickness and equation of surface microhardness) on the energy and technological parameters of ESA equipment, namely, discharge energy and labour intensity are developed that allows determining the main technological parameters of the formed layer: hardened layer thickness and surface microhardness.

Key words: electrospark alloying, coating, nitridation, steel, layer thickness, microhardness, mathematical model.
