Biomineralization behavior of Hap/CNTs/Ti6A14V into the simulated body fluid solution

Abstract

Hydroxyapatite doped carbon nanotubes (HAp/CNTs) was synthesized successfully as a coating on the surface of titanium alloy (Ti6Al4V) by a scanning potential method. The biomineralization of the materials soaked into a simulated body fluid (SBF) solution was investigated. The SEM images observed indicated that the formation of new hydroxyapatite crystals on the surface of Ti6Al4V with HAp or HAp/CNTs coating is better than that of Ti6Al4V. The formed hydroxyapatite crystals are confirmed by XRD result of Ti6Al4V after 21 soaked days in SBF solution. These results indicated that the coatings of HAp or HAp/CNTs have a good biomineralization.
