In the study, the 16 mm diameter and 6 mm thickness Ti6Al4V alloy (Grade 5) sample was used. The surfaces are metallographically prepared samples are made suitable for surface processing by cleaning with alcohol in the ultrasound bath. After the H2plasma pre-process, 0.15 M hydrofloric acid, 0.3 % NH4F and 2 % H2O containing ethylene glycol, 1M H2SO4 (Sulfuric Acid) and 1M H3PO4 (Fosphoric Acid) solutions were used as electrolytes for the anodic oxidation process, and the processes were carried out in 2 different voltage levels (20 V and 120 V) and 60 minutes of oxidation time. Electrochemical corrosion tests were carried out in the SBF (simule body fluid) solution for 1 hour waiting period. To determine the corrosion characteristics of the surface of the samples applied anodic oxidation process, the Table Extrapolarization and Linear Polarization methods, X-rays and Scream Electron Microscope (SEM) for surface characterization have been used. The scanned electron microscope was observed in the surface of the Ti6Al4V alloy that the ethylene glycol (EG) solution contained oxyts in the nano tube form, and the 0.15M hydrofloric acid (HF) solution contained porous oxyts. Electrochemical experiments have found that with the increase in the applied voltage, samples in the SBF solution have reduced corrosion resistance.
