| Popis: | cited By 2; International audience; The most important physico-chemical properties of materials with biomedical applications are: the morphology, the surface structure and the corrosion resistance. In this paper we follow the evolution of these properties, according to the conditions for obtaining TiO 2 coatings. These coatings were formed on titanium substrate by microarc oxidation (MAO). The electrolyte is a mixture consisting of β- glycerophosphate disodium salt pentahydrate and calcium acetate monohydrate. The obtained surfaces were characterized using scanning electron microscopy, X-rays analysis and corrosion tests. The anticorrosion properties of the layers were tested in biological environment (buffer solution) by means of electrochemical impedance spectroscopy (EIS), cyclic voltametry, Tafel tests. The results show a good electrochemical stability, combined with positive results regarding their biocompatibility. |
