摘  要:In the present study, electrochemical deposition of hydroxyapatite substituted with magnesium and strontium on Ti�C6Al�C4V alloy have investigated. Mg and Sr-doped HAp was coated using subsequently pulsed electrochemical deposition process at 85 ��C in the solution contained Ca, Mg, Sr, and P ion. The morphology of Mg/Sr-HAp formed on implant was investigated using scanning electron microscopy and X-ray diffraction. HAp grain size and XRD intensity decreased with Mg<sup>2+</sup> and Sr<sup>2+</sup> ions. The initial current density was changed with addition of Mg and Sr ion concentration when the constant voltage was applied to specimens. The morphologies and phase of HAp coated layers were affected by the Mg and Sr ion concentration. Results suggest that Mg/Sr-HAp layer formed on Ti can be a potential candidate for dental materials application.
