Abstract

A novel method to accelerate the apatite formation on the anodised titanium is proposed in this article. The processing was composed of two steps which were UV light treatment after anodic oxidation, and UV light illumination during simulated body fluid (SBF). This study aims to investigate the effect of UV light treatment condition on the apatite formation of anodised titanium. The titanium foils were anodised in mixture of β-glycerophosphate disodium salt pentahydrate (β-GP) and calcium acetate monohydrate (CA). UV light treatment was conducted in pH-adjusted distilled water (pH 1, 4, 7 and 11) for 12 hours. Next, SBF was carried out by illuminating with UV lamp for 1 week. Anodised titanium foils were characterised by using field emission scanning electron microscopy (FESEM), X-ray diffractometer (XRD) and goniometer. The results showed that donut-shaped were formed on the surface of anodised titanium. The surface of anodised titanium became more hydrophilic after UV-treated in acidic and alkaline condition. After UV light illumination in SBF for 1 week, the anodised titanium foils which UV-treated in acidic condition presented more crystalline bone-like apatite on the surface
