Abstract

We prepared titanium substrates with sub-micron scale pores and without sub-micron scale pores by means of chemical treatments with hydrogen peroxide and subsequent thermal treatments. Sub-micron scale pores were observed on the surface of the titanium substrate treated with 3 mass% H2O 2 at 90°C for 1 h(H1) by scanning electron microscopy. On the other hand, the sub-micron scale pores were not observed on the substrate treated with 3 mass% H2O2 at 90°C for 72 h(H72). The surface roughness, Ra of H1 and H72 substrates was 27 and 14 nm, respectively. Both substrates showed high in vitro apatite-forming ability in simulated body fluid (SBF of Kokubo's recipe). The apatite-forming ability of H72 substrate with low Ra value was higher than that of H1 with high Ra value.
