Abstract

Anodizing method was used to produce TiO2 nanotubes (TNTs) on Ti metal bases. These tubes were   transformed to lobed nanotubes (LNTs) by heating at 6000C as scanning electron microscopy (SEM) images showed. Rapid break down anodizing (RBA) technique was utilized to produce TiO2 nano particles (TNPs). These particles were deposited on LNTs by electrophoretic deposition (EPD) method. X-ray diffraction (XRD) test showed the polycrystalline composition of the formed LNTs and amorphous structure of TNPs. The bioactivity of LNTs and the deposited TNPs on the LNTs were tested by immersing them in simulated body fluid (SBF) for one month. For the two samples XRD patterns showed the appearance of small peaks of hydroxyapatite (HAp), which indicates the bioactivity of these samples. SEM images show that the HAp layer on LNTs was in the form of protrusions, while on TNPs it was in the form of crossed filaments.
