Anode plasma electrolytic nitrocarburizing of steel in an aqueous electrolyte based on glycerol, ammonium nitrate, and ammonium chloride

摘要

The mechanism of transport of saturating components from the electrolyte into the treated material during the anode nitrocarburizing of steel in an electrolyte containing glycerol, ammonium nitrate, and ammonium chloride has been described. The effect of the electrolyte component concentrations and treatment conditions on the pattern of formation and properties of the diffusion layers has been determined. The possibility of preparing a nitrocarburized layer with a thickness of up to 0.2 mm and a surface microhardness of up to 870 HV has been shown.
