Abstract

This paper relieves the elaboration and characterization of titania coatings formed on titanium by a relative new plasma electrolytic oxidation method (PEO). During the oxidation treatment, the titanium sample was immersed in electrolytic solution containing calcium acetate monohydrate ((CH3-COO)2Ca•H2O) and β-glycerophosphate disodium salt pentahydrate (C3H7Na2O6P * 5H2O) in distilled water. The obtained coatings were characterized using electronic scanning microscopy (SEM) and X-rays analysis (XRD). During the anodic oxidation changes not only the titanium surface topography but also the chemical composition and physical properties of the surface layers. The quality of titania coatings depend of the technique parameters, such as voltage, time, temperature etc. It can be observed that high quality coatings can be formed using properly selected deposition parameters..
