Abstract

The aim of this study is to develop bioactive-antibacterial coatings on Ti6Al4V using pulsed electrochemical technique. The deposition was carried out in a three electrode set-up within an electrolyte prepared by dissolving Ca(NO3)2 4H2O, NH4H2PO4 and Ag(NO3) in ultra-pure water. The paper aims to evaluate the effect of Ag addition on morphology, elemental and phase composition of hydroxyapatite coatings. The hydroxyapatite morphology has changed after silver doping, revealing a surface with agglomeration of spherical particles. Phase composition has confirmed the hydroxyapatite formation and, by adding Ag, the peaks have slightly shifted towards left, indicating that Ag is substituting the Ca present in the hydroxyapatite lattice.
