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.
