| Popis: | Uniform porous TiO2 film on Ti-6Al-4V alloy was obtained by hard anodic oxidation and successfully the chitosan layer was electrodeposited. Surface morphology, compositional properties and diffraction patterns were analyzed by scanning electron microscopy with energy dispersive X-ray analysis system and X-ray diffraction. The reactivity of anodic porous TiO2 film in the presence or absence of chitosan layer was investigated by electrochemical methods in biological solution and compared with the reactivity with the unmodified Ti-6Al-4V alloy surface. The electrochemical impedance spectroscopy method was used to compare the response reactivity of the three surfaces. The combination of the high biocompatibility of chitosan and good mechanical characteristics of Ti-6Al-4V alloy make the obtained porous TiO2 film combined with chitosan a promising method to improve the reactivity of medical implants in biological solution. |
