Abstract
A thermodynamic analysis of phase transformations taking place during doping of steel with tungsten and titanium has been performed. The studies on the surface layer of steel modified using the combined method (electrospark doping and the subsequent electron-beam treatment) have been carried out. Formation in the surface layer of a multi-phase submicrocrystalline structure with high strength properties has been revealed.

The method of electrospark doping (ESD), based on the phenomenon of electrical erosion and polar transfer of the anode material to a cathode during a pulsed electric discharge between them in a gaseous medium, differs from other surface treatment methods in its simplicity, reliability, and cost-effectiveness [1]
Depending on the anode material, an extended surface layer with high strength, tribological, and other properties is formed on the work piece
