Abstract

In the present study, the Ca-P coating layer on commercially pure titanium was fabricated using Micro-arc oxidation (MAO) method in electrolyte for osteointegrative coating (ESOC) at constant potential for different periods of time (0 - 600 minutes). The morphological microstructures, crystal structure and roughness of Ca-P coating layers were characterised by Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectrometer (EDS), X-ray Diffraction technique (XRD) and Atomic Force Microscope (AFM). SEM micrographs of treated samples demonstrated the microporous structure of Ca-P coating layer. Moreover, the results indicated that the number and size of micropores have increased with an increasing oxidation time. The contents of Ca and P on coating layer depend on the oxidation time. XRD results showed that the fabricated Ca-P coating layer contains Ti and hydroxyapatite (HA) phases at t = 600 minutes. AFM analysis showed that a mean roughness of untreated was 13 nm and treated samples ranging between 80-190 nm. Wettability property of an untreated and treated sample was hydrophilic which the magnitude was no different. © 2010 International Federation for Medical and Biological Engineering.
