“…Whereas, CPE can be applied on various kinds of substrate materials, such as metals, alloys, silicon and carbon. So far, various CPE techniques have been developed rapidly, such as surface cleaning [11], preparation of carbon nanotubes, diamond-like carbon films and diamond particles [12,13], carburizing, nitrocarburizing and borocarburizing [14][15][16], deposition of metal coatings [17][18][19] and ceramic coatings [20][21][22]. However, CPE techniques have to overcome the challenge from the high plasma discharge ignition current in the CPE process, so that CPE techniques could be widely used in industry.…”

h i g h l i g h t sElectron temperature in plasma electrolytic carburizing process is determined. Diffusion coefficient of carbon in PEC is higher than conventional carburizing. Wear and corrosion resistance of T8 steel are both improved after PEC treatment. Pitting corrosion of steel substrate is obviously suppressed by PEC treatment. t r a c tA hardening layer of 70 mm on T8 carbon steel was fabricated by plasma electrolytic carburizing (PEC) in glycerol solution at 380 V with 3 min treatment. The discharge process was characterized using optical emission spectroscopy (OES), and the electron temperature in plasma envelope was determined. Meanwhile, diffusion coefficient of carbon was calculated on the basis of carbon concentration profile. The tribological property of carburized steel under dry sliding against ZrO 2 ball was measured by a balldisc friction and wear tester. The corrosion behaviors were evaluated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). It was found that the carburized layer mainly contained a-Fe and Fe 3 C phases with maximum hardness of 620 HV. The PEC treatment significantly decreased the friction coefficient from 0.4 to 0.1. The wear rate of PEC treated steel was about 5.86 Â 10 À6 mm 3 /N$m, which was less than 1/4 of T8 steel substrate. After PEC treatment, the wear and corrosion resistance of T8 steel were improved. Particularly, the pitting corrosion of steel substrate was obviously suppressed.
