520			_aThe corrosion behavior of Ti, Ti-6Al-4V (TAV) and CoCrW in artificial saliva containing different NaF concentrations have been studied. Open circuit potential, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques were used. Also, the effects of saliva pH and immersion time of the studied materials in the test solution were taken into consideration. The corrosion rate of the three materials was found to increase with increasing fluoride concentration and decreased as pH increased. As the immersion time of the tested materials in 0.005 M NaF increases their passivity increase in the order CoCrW> Ti > TAV.The corrosion of the tested materials in serum depends on the surface conditions.Novel Coat was prepared composed of graphene oxide(GO) / chitosan(CS) /tricalcium phosphate(TCP)composite coating on Ti metal, Ti-6Al-4V and Co-Cr-W alloys in serum
