Bioactivity Treatments for Zirconium and Ti-6Al-4V Alloy by the Function of Apatite Nuclei

Abstract:

Micropores were formed on the surfaces of Zirconium (Zr) and Ti-6Al-4V alloy plates by soaking in sulfuric acid. In order to provide bioactivity to these metals, Apatite Nuclei (AN) were precipitated in the pores. By soaking in SBF, it was observed that the whole surfaces of Zr and Ti-6Al-4V alloy with the AN treatment were covered with the bone-like apatite within 1 day. The formed apatite layer showed high adhesive strength by a mechanical interlocking effect.
