The Effect of Electrolyte Composition on the Performance and Corrosion Resistance of Plasma Electrolytic Carbonitriding Films Formed on CP-Ti

Various nanocrystalline plasma electrolytic carbonitriding were done on commercially pure titanium in a Glycerol bath with different additives such as carbamide, natrium nitrate and triethanolamine. Effects of electrolyte composition on chemical composition and corrosion resistance of the PECIN films were examined by means of X-ray diffraction (XRD). scanning electron microscopy (SEM), potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) in Ringer solution. The results showed that the PECIN films obtained in solutions with triethanolamine (f -film) had better corrosion resistance.
