Anodic oxidation of titanium for biomedical application
Anodic oxidation is a chemical method which used to produce bioactive layer (oxide) of titanium (Ti). The aim of this study is to evaluate the effect of Ti anodic oxidation in an acetic acid (C2H4O2). The anodic oxidation was performed by varying the applied voltage (10 - 200 V) and the concentratio...

| Summary: | Anodic oxidation is a chemical method
which used to produce bioactive layer
(oxide) of titanium (Ti). The aim of this
study is to evaluate the effect of Ti anodic
oxidation in an acetic acid (C2H4O2). The
anodic oxidation was performed by varying
the applied voltage (10 - 200 V) and the
concentration of electrolyte (0.5, 1.5 and
3.0 M of C2H402). The Ti specimens were
soaked in simulated body fluid (SBF) to
observe the precipitation of hydroxyapatite
(HAP). The anodized Ti was characterized
using X-ray diffraction (XRrD) and
scanning electron microscopy (SEM). The
precipitation of apatite after soaked in SBF
was observed using SEM. From this study,
the applied voltage range from 100 to 200
V andlor high concentrations of acetic acid
resulting in more porous surface (show
peak formation of anatase) due to the
arcing process which lead more nucleation
(more sites for HAP growth) after soaked
in SBF. The SBF result shows that the
anodized Ti is suitable to be applied in
biomedical as implant. |
