Titanium and its alloys have a wide range of uses due to their outstanding properties such as high corrosion resistance, low density, high strength and easy formability. In addition, due to its high biocompatibility and elasticity close to bone, it has been accepted as a biomaterial and has very common use. Titanium and its alloys show good corrosion resistance in the open environment. However, due to the presence of various aggressive ions such as dissolved oxygen, chloride and hydroxide, the fluid in the body is exposed to high corrosion by being affected by the corrosive environment that occurs. Therefore, various surface treatments are applied to increase the lifetime of titanium and its alloys. In this study, the surface of Ti45Nb alloy was coated by adding SiC into the PEG (Polyethylene glycol) / PU (Polyurethane) mixture using the dip coating technique. The coating process was carried out by immersing the samples in the coating solution for different times of 5-15-30-45 minutes. The samples were subjected to corrosion test in SBF solution, and Open Circuit Potential (OCP), Electrochemical Impedance Spectroscopy (EIS) and potentiodynamic polarization measurements were made. As a result of the corrosion test, it was observed that the corrosion resistance of the coated surfaces increased compared to the untreated sample, and the corrosion resistance increased with the increase of the coating time.
