چکیده مقاله:
Hydroxyapatite (HA, Ca۱۰(PO۴)۶(OH)۲) has been widely used as a coating material for dental implants for many years, due to its close similarity of chemical composition with bone material and its ability to bond with bone. In this study, a hydroxyapatite coating was formed on Ti substrate, employing the electrochemical coating method of cyclic voltammetry, in order to enhance the corrosion resistance. Formation of Hydroxyapatite on Ti is confirmed by the XRD and SEM analyses. Polarization curves revealed a substantial improvement in the corrosion potential from -۲۸۹ to -۱۹۳ mV (Ag/AgCl) and decrease in corrosion-current density, for the hydroxyapatite coatings in artificial saliva compared with pure titanium that showed positive role of HA on Ti corrosion behavior
