Electrochemical preparation of ordered nano HAp coatings on Ti substrate and in vitro study on its bioactivity

Abstract

The HAp coatings with various surface morphologies were electrochemically deposited on titanium to improve its bio-properties. We compared the bio-properties for the different surface morphology coatings on titanium through a detailed surface characterization and upon in vitro cellular response of osteoblast-like cells MG63. The results of in vitro cellular response indicated that the uniform porous morphology of HAp layers on titanium exhibited higher bioactivity than the needle-like ones.
