Abstract To improve the corrosion performance of titanium and titanium alloy in human body and Marine environment,the Ta-10W coating was prepared on the commercial pure titanium (CP-Ti) and TC4 matrix by multi-arc ion plating. The corrosion resistance of the coating in simulated human body and Marine environment was studied by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), electrodynamic polarization and electrochemical impedance spectroscopy (EIS) test. The results show that the Ta-10W coating is continuous, dense with uniform thickness. The mainly phase is body-centered cubic α-Ta. Ta-10W coated samples corrosion potential is higher and corrosion current density is lower in ringer solution and simulated seawater solution. The Ta-10W coating on CP-Ti reduces the corrosion current density to 2.648×10-9 A/cm2 in ringer solution and 2.548×10-9 A/cm2 in simulated seawater solution, which is an order of magnitude lower than that of CP-Ti matrix, and also has excellent improvements on TC4 matrix. In addition, Ta-10W increases the charge transfer resistance of CP-Ti and TC4 by 1 or 2 orders of magnitude in the two solutions. The dielectric property of the double layer is also improved by coating Ta-10W, thus the corrosion resistance of CP-Ti and TC4 in different solution environments is effectively improved. Therefore, Ta-10W coating has a good protective effect on the corrosion resistance of CP-Ti and TC4 in human body and marine environment, and is instructive for the application of titanium and titanium alloy in these environments.
