Calcium phosphate coatings have been generally considered as an effective approach to providing the metal implants with good biocompatibility and osteoconductivity.In addition,zinc element has been proved to stimulate bone formation and bone mineralization in tissue culture.Thus,in this research,we report a facile preparation of zinc-calcium phosphate coating on titanium(Ti)used phosphate chemical conversion(PCC)method in order to enhance the surface biocompatibility and corrosion resistance of Ti.The results indicate that the coating is mainly composed of scholzite(CaZn2(PO4)2·2H2O)with minor hopeite(Zn3(PO4)2·4H2O)with a radial flower-like micro-nano structure.Electrochemical measurement reveals that the coated Ti sample exhibits better corrosion resistance than the naked substrate.The immersion of SBF(simulated body fluid)indicates that after immersion of 15 days in SBF,the crystals of scholzite are degradable and fine particles of HA(hydroxyapatite)are deposited on the surface of scholzite coating.
