Most publications are associated with questions of metal science, including the phase composition, structure, hardness and the roughness of the modified layer, as well as the characteristics of wear and corrosion resistance. Less attention is paid to the electrochemical aspects, in particular, reactions that Pyridostatin determine the influence of the electrolyte on the structure of the modified layer and also to studying the transport of nitrogen and carbon, etc. It was found that the sizes of the sample plot modified by the action of the pulse discharge increase with the potassium hydroxide concentration under conditions of the pulse cathode PEN/C. The peak intensity of the iron nitride and chromium iron carbide (Cr2Fe14C) is reduced with increasing concentration of KOH after PEN/C. The more powerful, but rarer discharge channels decrease the overall treatment area according to Kong et al. .
There is a hypothesis of the decomposition of carbamide to nitrogen and carbon proposed by Nie et al. , wherein the carbon donor is carbon dioxide. However, the chemical inertness of carbon dioxide gives grounds for doubt. Carbon dioxide is suggested to decompose in strong electric fields  but it should be noted that carbamide is an effective source of carbon in the case of anode PEN/C with no visible electric discharges .
