Corrosion properties of ECAP titanium with bioactive oxide coating in physiological solution

Popis výsledku v původním jazyce

This paper aims to comparison of corrosion properties of CP and ECAP titanium samples with different grain size. These alloys are commonly used in implantology for manufacturing long term body hard tissues replacements. Surfaces of tested samples were also electrochemically anodized using solution containing fluorine ions. the main reason for anodization was to create surfaces with highly bioactive properties which can intensify healing process and result into better bonding between body tissues when they are used in implantology. It was found by standard electrochemical methods that difference of corrosion rate between anodized and non-anodized samples was not significant. Anodization results positively influenced decreasing of corrosion rate when samples were tested in aerated isotonic physiological solution (0,9 wt. % NaCl/water). Type of bonding between implant and surrounding tissue may be also predetermined by value of contact angle of tested sample and water droplet on its surface. This paper confirmed that anodization increases wettability of tested samples and lower the contact angle to ~60o. According to these results anodization process may be recommended as a profitable treatment for surfaces of hard tissue replacements made from titanium.
