Abstract

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.
