Abstract
Ti-15Mo-5Zr-3Al alloy, with lower elastic modulus in comparison with Ti-6Al-4V alloy, was treated with H2SO4 solution to form pores on its surface. In order to provide apatite-forming ability to the alloy, apatite nuclei were precipitated in the pores using simulated body fluid with higher pH value in comparison with the conventional one. By this treatment, a bioactive Ti-15Mo-5Zr-3Al alloy was obtained. The apatite-forming ability of the bioactive Ti-15Mo-5Zr-3Al alloy was evaluated by soaking in SBF. In addition, adhesive strength of the bone-like apatite layer formed in the SBF was measured.
