Hodgson, Cuie Wen ⁎ Centre for Material and Fibre Innovation, Deakin University, Waurn Ponds, Victoria 3217, Australia A R T I C L E I N F O A B S T R A C T Article history: Calcium phosphate (Ca-P) coatings were deposited on Ti substrates by a biomimetic method from m-SBF and Received 16 April 2008 10× SBF, respectively. Comparative study of microstructures and bond strengths of the Ca-P coatings Received in revised form 5 June 2008 deposited from those different SBFs was carried out. Effect of the surface roughness of the substrates on the Accepted 7 June 2008 bond strength of the Ca-P coatings was also studied. Scanning electron microscopy (SEM), X-ray Available online 12 June 2008 diffractometry (XRD), Fourier transformed infrared spectroscopy (FTIR), inductive coupled plasma spectro- Keywords: metry (ICP) and thermogravimetry (TG) were used to characterize the Ca-P coatings. The bond strengths Calcium phosphate (Ca-P) between the coatings and Ti substrates were measured using an adhesive strength test. Results indicated that Titanium (Ti)
