Abstract

Ca (CH₃COO)₂ · H₂O-Ca(H₂PO₄) · H₂O electrolyte system with La (NO₃)₃ · 6H₂O was used to carry out micro-arc oxidation treatment on pure titanium. By means of XRD, SEM and EDX, the effects of La on morphologies, phases and compositions of coatings gained from the electrolyte were investigated. The cell culture method was used to study the cyto-compatibility of the coating. The results show that the coatings formed in electrolyte with La are thinner and have larger pores than those formed in electrolyte without La. Addition of La can inhibit the transition from anatase to rutile and has stronger capability of inducing HA. After being sintered, the amorphous hydroxyapatite (HA) in coatings is crystallized into flake or scaly. The new coatings after being sintered with HA/TiO₂ are proved to have good biocompatibility.
