Kinetics and mechanical study of plasma electrolytic carburizing for pure iron

▶ This study was driven by the lack of studies on the plasma electrolytic surface carburizing of pure iron. ▶ At the present study, the pure iron samples were carburized in aqueous solution of 20% glycerin. ▶ The samples were carburized at 750 °C, 800 °C, 900 °C and 950 °C temperatures for 5, 10 and 30 min. ▶ The effect of temperature, time and the amount of glycerin on the kinetics of this process was evaluated.
