Abstract
The aim of the present study is to prepare the bovine hydroxyapatite-diopside (bHA-Di) nanocomposite coating using electrophoretic deposition (EPD) technique and then investigation of the bioactivity, wettability and hardness of the produced coating samples at different percentage of Di. For this purpose the HA powders is prepared from the bovine bones by a simple new method and then Di powders that have already synthesized by the use of mechanical milling method, is injected into the HA matrix. At the end a suspension of the bHA-Di nanocomposite is created and coated on the titanium (Ti) implants by the EPD technique. The sintered nanocomposite coating are then sintered and analysed. X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and differential scanning calorimetric (DSC), energy dispersive spectroscopy (EDS) and inductive coupled plasma atomic emission spectroscopy (ICP-AES) are used as instruments for gathering and analysing the experimental results. According to the results obtained, the produced composite coating with 30 wt. % Di has favourable bioactivity, good wettability and high hardness.
