STUDY OF PULSE ON PULSED NANOCRYSTALLINE PLASMA ELECTROLYTIC CARBONITRIDING ON THE NANOSTRUCTURE OF COMPOUND LAYER
Surface hardening of commercially pure titanium by using pulse on pulsed nanocrystalline plasma electrolytic carbonitriding has been studied in this investigation. Coating process has been performed on Triethanolamine-based electrolyte by cooling bath. Nanostructure of obtained compound layer was examined with figure analysis of SEM nanographs. The effects of process variables, i.e., Triethanolamine concentration, electrical conductivity of electrolyte, applied voltage, and treatment time, have been experimentally studied. Statistical methods were used to achieve the optimum size of nanocrystals. Finally the contribution percentage of effective factors of pulsed current was revealed and confirmation run show the validity of obtained results.
