Anode plasma electrolytic saturation of low-carbon steel by carbon, nitrogen, boron, and sulfur
Possibility of simultaneous saturation of low-carbon steel by carbon, nitrogen, boron and sulfur at the anode plasma treatment in aqueous electrolyte with ammonium chloride, carbamide, boric acid, and sodium thiosulfate is shown. Results of SEM/EDX semiquantitative elemental microanalysis of the surface oxide and diffusion layers are presented. The surface microhardness of the hardened layer reaches 600 HV after treatment at 800°С with following quenching.
