Abstract:

A hydroxyapatite coating on the porous titanium surface was prepared by NaOH-treated and heat treatment followed by immersing into a supersaturated calcium phosphate solution. It is found that the porous titanium was in an open-cell microstructure. The morphology, element content and phase composition of the hydroxyapatite coating were also analyzed. The cytotoxicity of porous titanium surface were tested. The results showed the hydroxyapatite of porous titanium surface by NaOH-treated and heat treatment was attached uniformly and had a certain thickness after immersion into the simulated body fluid (SBF) solution for 5 days, the hydroxyapatite coating was formed after immersion into the SBF solution for 12 days, it demonstrated good biocompatibility and enhancement of biological activity, it was conducive to the proliferation and adhesion of osteoblasts.
