In this paper modified gradient layer was under research, the resulting electrolytic-plasma carbonitriding of low carbon steel 18CrNi3Mo surface was investigated. Aiming to improve the structure and strength properties of the layer, the possibility of application have been shown. Plasma carbonitriding optimized mode is presented as well. Regime of electrolyte plasma carbonitriding which consists in heating the steel sample to 8500C with aggregate exposure at this temperature for 3-7 min. and quenching in cold electrolyte has been optimized. We studied the processes of modified layer structure formation under different conditions
