Synthesis and in vitro electrochemical study of composite coatings on implant by electrophoretic deposition

Abstract

The aim of the present study is the preparation and characterization of silicon dioxide, zinc oxide and it's composite. The above inorganic biomaterials were synthesized by sol-gel method. The nosocomial Infections or a hospital-acquired infection of an implant (biofilm) dramatically increases the risk of orthopaedic Implant surgery. The biofilm infections of an implant or prostheses can be preventable with better surface modification of bioactive and corrosion resistance composite coatings of 70% SiO2with 30% ZnO by electrophoretic deposition (EPD). The prepared powders and its coatings were characterized by Powder X-ray diffraction, in vitro electrochemical studies such as Tafel polarization and electrochemical impedance analyses.
