Abstract：Objective:To study the effect of TiN film by pulsed bias arc ion plating technique on the corrosion resistance of casted titanium in fluoride environment. Methods:Potentiodynamic polarization technique was used to measured the currentdensity of corrosion (Icorr)and the electric potential of corrosion (Ecorr)of untreated and TiN-coated casted titanium in the artificial saliva with 2000mg/L fluoride concentration.After electrochemical experiment, the microstructure was observed by scanning electron microscope (SEM ). Results:The Icorrs of untreated and TiN-coated titanium were 4.13±0.19 and 0.66±0.03μA respectively.The Ecorrs were-0.57±0.05 and-0.50±0.03V respectively.The Icorrs of TiN-coated titanium were significantly low er than untreated titanium and the E corrs of TiN-coated titanium were significantly higher than untreated titanium . The surface of untreated titanium was corroded m ore heavily than TiN-coated titanium . Conclusion:The corrosion resistance of titanium were increased significantly after pulsed bias arc ion plated TiN-coated .
