ABSTRACT

The purpose of this study was to investigate the formation of apatite layer on two different titanium substrate treated with biomimetic method. Titanium plates were heat-treated at different temperatures of 400oC, 600oC, and 800oC for 5 h in air atmosphere. And then, that plates were chemically treated with an alkali solution of 1M sodium hydroxide(NaOH). The pre-treated titanium plates were soaked in the simulated body fluid (SBF) of Kokubo's recipe. After soaking for 7 days and 21 days in SBF, the coated layers formed on the titanium plates were characterized and compared with the morphology and chemical composition. The apatite formation was more activated on the titanium plates chemically treated with NaOH compared with the only heat-treated titanium plates.
