Abstract:
      In this thesis, a fluorine-doped hydroxyapatite (FHAP)/Micro-arc oxidation (MAO) composite coating is deposited on commercially pure titanium (CPTi) surface through micro-arc oxidation and electrochemical deposition (ED) technique. Simulative Hank"s solution is used to test the electrochemical corrosion resistance of uncoated CPTi substrate and coated samples. The impact of MAO interface layer on the micro-structural, mechanical property, and electrochemical property of coating is studied in this article. Results show that the deposited HAP/Ti, FHAP/Ti and FHAP/MAO/Ti coated samples dramatically improved the anticorrosion of the CPTi substrate in the simulative Hank"s solution. However, the mechanical properties testing show that FHAP/Ti coating has a poor bonding strength of 10.7 MPa compared to that of FHAP/Ti coating with a MAO interface layer (18.1 MPa). Furthermore, the contact angle of the FHAP/MAO/Ti coating with deionized water is approximately 35.8°, which is more beneficial to promote cell attachment and proliferation.
