Abstract

ECAP titanium of lower grades with extra fine grains may be used for manufacturing of highly loaded implant or their parts and presents excelent replacement of strandartly used Ti-6Al-4V alloy. This type of material aslo showes excelent corrosion properties ang high level of biocompatibility, which can be even impoved by different surface treatment. This paper deals with possibility oxidic anodization as a method of creation highly organised nanostructures on implant surface and further chemical treatment of anodized layer in acid/alkaline solutions. It was proved that chemical treatment increases content of specific ions in anodized structure, which will leads into more effective osteointegration process while not affecting its of corrosion properties, which was tested by potentiodynamic polarization methods in artificial isotonic physiological solution according ASTM standards for implants. On the other hand chemical treatment positively affects wettabilility resp. surface energy of studied samples. Many previous studies focused on osteointegration process confirmed that lower values of contact angle directly corelate with effectivity of ossteointegration process and a relation between preferred induced type of organic tissue and implants surface energy has been previously published. Presented procedures of surface treatments shows promising results and might find its use in commertial implants manufacturing
